Low-Maintenance Perennial Flowers: 10 Easy Picks for Any Climate

Perennials are the backbone of any low-effort garden. Plant them once, and they return year after year — some for decades — filling borders, attracting pollinators, and looking beautiful with nothing more than the occasional trim. But “low-maintenance” means very different things depending on where you garden. A plant that thrives with zero care in the Pacific Northwest might struggle and die its first winter in a Minnesota yard, or cook itself to death in a Phoenix summer. The flower seeds on this list were chosen because they genuinely earn the low-maintenance label across a wide range of climates — not just one.

These 10 perennials cover everything from blazing full sun to deep shade, from Zone 2 winters to Zone 9 heat. Several have double-duty value as medicinal herbs, wildlife attractors, or cut flowers. And crucially, most can be started from seed — giving you a much cheaper and more satisfying path to a full garden than buying transplants every spring.

What Actually Makes a Perennial Low-Maintenance?

The term gets thrown around loosely, but genuine low-maintenance perennials share a specific set of traits. They establish quickly from seed or transplant, tolerate a range of soil conditions without amendment, rarely need dividing in the first several years, and resist the most common pests and diseases in their target zones. They either self-deadhead or bloom reliably without it. And critically — they’re adapted to survive your local winters without protection.

What they’re not: plants that need staking, weekly watering, annual lifting and storage (like dahlias or gladiolus), or that go dormant in a way that leaves a gap in your garden for half the season. The 10 on this list meet the standard honestly. A few come with one honest caveat — noted where it matters — because no plant is maintenance-free in every single climate.

1. Echinacea (Coneflower) — The Workhorse

Echinacea seeds — also known as purple coneflower — are among the easiest perennials to establish from seed, and the plant rewards that investment for 10 or more years. Echinacea blooms from June through September, handles clay and sandy soils equally well, and tolerates drought once established. The daisy-like flowers in shades of pink, purple, white, and gold attract bees, butterflies, and goldfinches — birds eat the seed heads through autumn and winter, giving you wildlife value even after blooms fade.

Echinacea also carries real medicinal credentials. The roots and flowers are widely used in herbal preparations for immune support, making this genuinely one of the most dual-purpose plants in the perennial garden. It self-seeds modestly without becoming aggressive, filling gaps in the border each year. For low-effort gardeners, the only task is cutting plants back in late fall or leaving them standing for winter bird feeding — both are correct choices.

For a complete growing guide, see How to Grow Echinacea from Seed.

2. Daylily (Hemerocallis) — The Unkillable Spreader

Daylilies are about as close to indestructible as garden plants get. They tolerate drought, wet soils, clay, sand, part shade, and neglect with a resilience that borders on miraculous. Once established, a clump expands steadily year after year, eventually providing enough divisions to fill an entire border for free. The trumpet-shaped flowers in orange, yellow, red, purple, and multicoloured bicolors bloom in waves from early to late summer depending on variety — choose early, mid, and late-season types to keep colour going for two full months.

One honest note: daylilies grown from seed take two to three years to bloom and produce variable results compared to the parent plant. Most gardeners start daylilies from divisions. That said, the division process is one of the easiest in gardening — dig a clump in spring or fall, pull it apart with your hands or a fork, and replant. The real low-maintenance play here is planting once and dividing for free every few years rather than buying new plants.

3. Black-Eyed Susan (Rudbeckia) — The Self-Seeder

Black-Eyed Susans bloom from mid-summer well into fall, filling that late-season gap that many perennials leave behind. The golden yellow petals with dark brown centres are cheerful and unmistakable, and they attract native bees, butterflies, and finches in numbers that make them one of the most pollinator-valuable plants you can put in a border. They’re drought-tolerant once established, handle poor soil well, and — critically — self-seed readily, meaning a single plant becomes a colony over two or three seasons without any help from you.

Rudbeckia fulgida ‘Goldsturm’ is the most reliably perennial variety across zones 3–9. Some species, like R. hirta (the common Black-Eyed Susan), behave as short-lived perennials or biennials — they bloom heavily in year two, set seed, and the parent plant often dies, but the seedlings fill the gap so quickly you won’t notice. Understanding this distinction saves frustration: if your plant looks dead after two big bloom years, it’s not a failure, it’s the plant’s life cycle working as intended.

4. Lavender (Lavandula) — The Fragrant Drought-Buster

Lavender earns its low-maintenance reputation in the right conditions: full sun, excellent drainage, and alkaline to neutral soil. In those conditions it asks for almost nothing — a light shear after bloom, no fertilizer, and occasional deep watering during the first season. After establishment, it handles drought better than nearly any other flowering perennial, making it the ideal choice for hot, dry gardens in Zones 5–9.

Both English lavender and French lavender are worth growing from seed, though germination is slow (3–4 weeks) and benefits from a cold stratification period. English lavender (Lavandula angustifolia) is the hardier choice for colder zones and is the source of the classic culinary and medicinal fragrance. French lavender (Lavandula dentata) is showier and blooms longer but tops out around Zone 7–8. One common mistake — especially in Zones 5 and 6 — is mulching lavender crowns for winter protection. This traps moisture around the crown and causes rot. Lavender prefers to overwinter exposed with good airflow; the cold is rarely the problem, the wet is.

For more detail, see our complete lavender growing guide.

5. Yarrow (Achillea millefolium) — The Poor-Soil Champion

If you have a sunny spot with thin, rocky, or sandy soil that defeats everything else, plant yarrow. It actively dislikes rich, fertile soil — too much organic matter causes floppy stems and rank growth that needs staking, defeating the whole low-maintenance premise. Yarrow in lean, well-drained soil stays compact, stands upright without support, and blooms prolifically in white, yellow, pink, and red from early summer through fall. It’s one of the best candidates for dry slopes, gravel gardens, and hellstrip plantings.

Yarrow is also one of the most ecologically valuable plants on this list. The flat-topped flower clusters are landing pads for predatory wasps and parasitic insects that prey on garden pests — plant it near vegetables and it functions as a biological pest control system. It spreads by underground rhizomes and self-seeds, so give it space to expand or divide it every few years. Short-lived in very humid climates (Pacific Northwest, Gulf Coast) where powdery mildew can set in — spacing plants widely for airflow fixes this in most cases.

6. Sedum (Stonecrop) — Extreme Drought Tolerance

Late-blooming sedum fills the September–October gap when most other perennials are winding down, and does so with essentially zero care. The tall border sedums (Hylotelephium, formerly Sedum, including the classic ‘Autumn Joy’) form attractive succulent rosettes all summer before producing broad, flat flower heads that open pink and age to copper-red through fall. Butterflies and native bees depend heavily on these late-season flowers when few other nectar sources remain.

Sedum’s two standout traits are drought tolerance that approaches cactus-level and strong deer resistance — both especially valuable in rural and suburban areas across the Upper Midwest, Northeast, and Ontario where deer pressure is intense. It thrives in gravel, poor soil, and full-sun spots that bake in summer. The one failure mode to know: sedum in rich, shaded, or wet soil grows too fast, flops open at the centre, and needs staking. Plant it lean and sunny and it never needs any support.

7. Shasta Daisy — Long Season, Great Cut Flower

Shasta Daisies deliver the longest bloom window on this list — a well-managed clump can produce white flowers with golden centres from June through September, especially if you deadhead the first flush. The plant is technically a short-lived perennial in some climates, behaving more like a biennial in Zones 4–5, but it self-seeds so readily that you’ll have continuous new plants filling any gaps. In Zones 6–9 it persists reliably for many years.

Shasta Daisies are one of the easiest perennials to start from seed, often blooming in their first or second year if started indoors 6–8 weeks before last frost. They prefer full sun and well-drained soil, tolerate modest drought once established, and make excellent cut flowers — harvesting stems extends bloom time rather than reducing it. Divide every 2–3 years in early spring to keep the centre from dying out, a task that takes about ten minutes and produces free plants to spread around the garden.

8. Coral Bells (Heuchera) — Best Foliage Perennial

Coral Bells are grown primarily for their striking foliage — available in colours ranging from lime green to deep burgundy to near-black — which provides all-season interest even when they’re not in bloom. The delicate, wiry stems of small bell-shaped flowers that appear in late spring are a bonus, attracting hummingbirds and native bees. Heuchera is among the few perennials in this guide that genuinely tolerates part shade to full shade, making it ideal for north-facing borders, woodland edges, and spots under deciduous trees.

Growing Coral Bells from seed produces variable foliage colours compared to named cultivars (which are propagated vegetatively), but the seed-grown plants are perfectly garden-worthy and often produce surprising colour mixes. Sow seeds on the surface of a moist seed-starting mix — they need light to germinate — and don’t cover them. Coral Bells is relatively short-lived (3–5 years) in heavier clay soils, but division in early spring extends plant life and gives you plenty of new starts. In warm climates (Zones 7–9), they appreciate afternoon shade to prevent leaf scorch.

9. Peony (Paeonia) — The Long-Term Investment

Peonies are not a plant for impatient gardeners — established from bare root or divisions, they may take 2–3 years to bloom well; grown from seed, expect 3–5 years. But the payoff is extraordinary: a single peony planting can live and bloom reliably for 50 to 100 years, outlasting the house it was planted beside. The large, fragrant flowers in pink, red, white, and soft yellow are among the most spectacular in any perennial border, blooming in late May to June with a scent that’s hard to match.

Beyond the patience required at planting, peonies are genuinely low-maintenance. They need good drainage, full sun (at least 6 hours), and to be planted with the eyes (buds) no more than 2–5 cm (1–2 in) below the soil surface — plant too deep and they will not bloom, a mistake that’s more common than it should be. They don’t need dividing for decades. Botrytis (gray mould) can be a problem in wet springs — cutting stems to the ground in fall and removing them from the garden prevents it almost entirely. Zones 3–8; they actually require cold winters to set buds properly, which means they’re not suited to Zones 9–10.

10. Hosta — The Shade Garden Solution

Hostas solve a problem that most other perennials can’t: they thrive in deep shade. Under trees, on north-facing slopes, in the shadow of fences and structures where little else grows, hostas provide lush, textural foliage in sizes from teacup-small to dinner-plate-enormous. Leaves come in green, blue-green, gold, and variegated combinations, providing multi-season interest even when the lavender or white summer flowers aren’t present.

A note on seed-growing: most hostas sold commercially are sterile hybrids or named cultivars propagated by division, not seed. Seed-grown hostas are possible — they germinate readily with bottom heat — but will produce variable plants quite different from the parent. If you want a specific named variety, buy a division. That said, seed-grown hostas are perfectly beautiful garden plants, and starting them from seed is a slow but rewarding process for patient gardeners. One genuine maintenance task: slugs. Large-leafed hostas are slug magnets in wet climates. Planting near stonecrop sedum or using iron phosphate bait reduces damage significantly without chemicals. Deer also favour hostas heavily — in high-deer-pressure areas, choose the thick-leaved blue varieties (like ‘Halcyon’) which are browsed less frequently.

Growing Perennials from Seed: What the Nursery Doesn’t Tell You

Starting perennials from seed is dramatically cheaper than buying transplants — a $5 seed packet can produce 50–100 plants that would cost $8–15 each at a nursery. The catch is time: most perennials don’t bloom in their first year, and some take two to three seasons to reach full size. But once established, they’re yours for decades, and you’ll have divisions to share rather than plants to buy.

The best technique for cold-hardy perennials like echinacea and yarrow is winter sowing — fill milk jugs or deli containers with potting mix, sow seeds in December or January, leave them outside, and let freeze-thaw cycles do the stratification work naturally. Seeds germinate in spring exactly when they’re ready, producing tough, already-hardened seedlings that outperform anything started indoors.

Climate Realities: What “Low-Maintenance” Actually Means in Your Region

Every plant on this list is described as low-maintenance in standard growing references — but those references were usually written for a temperate mid-Atlantic or Pacific Northwest climate. Here’s what actually changes depending on where you garden.

🥶 Cold/Short-Season Climates

Canada Zones 2–5 | US Upper Midwest, Northern Plains, Mountain West (high elevation)

Your biggest perennial asset is cold-hardiness, and most of this list delivers — echinacea, yarrow, black-eyed susan, daylilies, sedum, and hostas all survive Zone 3–4 winters without protection. Peonies actually need cold to bloom properly and are among the best perennials for short-season climates.

The adjustment: lavender is marginal in Zone 5 and unreliable in Zone 4 — mulch the crown lightly with gravel (not bark, which holds moisture) and choose English lavender over French. Shasta daisy behaves as a biennial in Zone 4–5 and needs self-seeding space to perpetuate. Plant in early May after last frost; don’t rush. Winter sowing is the single best seed-starting technique for cold-climate gardeners — it uses natural freeze-thaw stratification and produces seedlings timed exactly to your spring.

💧 Humid/High-Pest Climates

Southeast US, Gulf Coast, Mid-Atlantic, Southern Ontario, Pacific Northwest

Humidity is the enemy of several plants on this list. Lavender in particular struggles — crown rot from wet winters kills more lavender in Zone 7 humid climates than cold ever does. Plant on raised beds or slopes, use gravel mulch, and avoid watering once established. Yarrow gets powdery mildew in humid settings; wide spacing (45–60 cm / 18–24 in) dramatically reduces this.

Echinacea and black-eyed susan are at their best in humid climates — they’re native to the Eastern prairies and handle humid summers well. Hostas in the Southeast need afternoon shade from intense heat even if technically in their zone range. Shasta daisy thrives in the Pacific Northwest and Mid-Atlantic. Coral bells is excellent in Part-shade Pacific Northwest gardens where it stays cool and moist. Watch for botrytis on peonies in wet springs — fall cleanup is the fix.

☀️ Arid/Heat-Stress Climates

Southwest US, Southern Plains, Texas, Low Desert (AZ, NV, Southern CA), BC Interior

Drought tolerance is the primary filter here. Your top picks from this list: sedum, yarrow, black-eyed susan, and echinacea — all handle dry conditions well once established. Lavender is outstanding in dry Mediterranean climates and the BC interior.

What to avoid or modify: hostas need regular irrigation in hot-dry climates and will burn without afternoon shade. Peonies don’t perform well in Zones 9–10 because they need cold winters to set buds — if you’re in the low desert, skip peonies. Shasta daisy benefits from afternoon shade in temperatures above 35°C (95°F). Daylilies tolerate heat but need supplemental water in their first year in dry climates — after establishment, they manage well. In extreme heat, water newly planted perennials deeply twice a week for the first full season, then taper off in year two.

Companion Planting with Perennials

Perennials aren’t just ornamental — the right combinations create ecological systems that reduce pests, attract pollinators, and keep the garden healthier with less intervention from you. The companion relationships below are based on documented ecological interactions, not garden folklore.

Frequently Asked Questions

❓ Perennial Flowers FAQ
What is the difference between a perennial and an annual flower?
An annual completes its entire life cycle — germination, growth, flowering, seed set, death — in a single growing season. A perennial lives for three or more years, dying back to the ground in winter (in most climates) and regenerating from its root system each spring. Biennials are a middle category: they germinate and establish in year one, bloom and set seed in year two, then die. Some “short-lived perennials” like shasta daisy blur the line, behaving as biennials in colder zones but persisting for several years in warmer ones.
Which perennial flowers are the easiest to grow from seed?
Black-eyed susan, yarrow, and shasta daisy are the easiest on this list — they germinate readily without special treatment and often bloom in their first or second season. Echinacea is slightly more involved because it benefits from cold stratification, but the winter-sowing method makes this effortless: sow seeds in containers outdoors in December or January and let natural freeze-thaw cycles do the work. Lavender is the most demanding — slow to germinate, needs surface sowing with light, and takes time to establish.
Which perennials survive Canadian winters (Zone 3–4)?
The most reliable Zone 3–4 perennials on this list are echinacea, yarrow, black-eyed susan, daylilies, sedum, hostas, and peonies — all rated to Zone 3. Peonies are exceptional cold-climate plants and actually require several weeks of freezing temperatures to bloom properly. Coral bells is reliable to Zone 4. Shasta daisy can be iffy in Zone 3–4 but self-seeds to fill gaps. Lavender is the weakest performer in cold climates — English lavender survives Zone 5 reliably, marginal in Zone 4, and not recommended for Zone 3.
How do I know when to divide my perennials?
The two clearest signs are a dying-out centre (common in shasta daisy, echinacea, and black-eyed susan) and a significant drop in bloom quantity despite good growing conditions. Most perennials benefit from division every 3–5 years. The timing rule is simple: divide spring and summer bloomers in early fall; divide fall bloomers in early spring. Use a sharp spade to cut the clump into sections, each with several healthy shoots and roots. Replant immediately at the same depth and water well through the first season.
Do low-maintenance perennials need fertilizer?
Most of the plants on this list actively dislike fertilizer — yarrow, sedum, and lavender all produce weaker, floppier growth in rich soil. A single application of compost worked into the soil at planting time is sufficient for most perennials, with perhaps a light top-dressing every two to three years. The exceptions are daylilies and peonies, which respond well to a balanced slow-release fertilizer in early spring. Heavy fertilization of any perennial typically produces lush foliage at the expense of flowers, and makes plants more susceptible to fungal disease.
Which perennials on this list are deer-resistant?
Lavender, yarrow, and sedum are among the most reliably deer-resistant plants available in any category — deer avoid aromatic foliage and succulent textures. Echinacea and black-eyed susan are moderately resistant; deer may browse them but rarely decimate a planting. The most vulnerable on this list are hostas (especially thin-leaved varieties), daylilies, and coral bells — all are readily browsed in high-deer-pressure areas. If deer are a serious problem, focus your planting on lavender, sedum, and yarrow as the backbone, and choose thick-leaved blue hosta varieties which are browsed less frequently than green or gold types.
What perennials bloom all summer?
No single perennial truly blooms all summer — each has a peak window of 4–8 weeks. The key is combining plants with staggered bloom times to create the appearance of continuous colour. From this list: peonies and coral bells (late spring); daylilies, lavender, and echinacea (early-to-midsummer); shasta daisy and yarrow (midsummer); black-eyed susan (mid-to-late summer); sedum (late summer to fall). Plant at least one representative from each window for a garden that appears to bloom continuously from May through October.
Should I cut perennials back in fall or leave them standing?
Leaving most perennials standing through winter provides significant wildlife value — echinacea and black-eyed susan seed heads feed finches and sparrows into January in colder climates. The stems and spent foliage also provide overwintering habitat for native bees. The exception is plants prone to fungal disease: peony stems must be cut to the ground and removed from the garden (not composted) in fall to prevent botrytis. Daylily foliage can be cut or left — it decomposes quickly either way. A good middle approach is to cut back in early spring rather than fall, leaving structure through winter and tidying just as new growth begins.
Which perennials attract the most pollinators?
Echinacea, black-eyed susan, and yarrow are consistently among the top-rated native pollinator plants in North America — all three are native species or close relatives of native species, which makes them far more valuable to native bees than introduced ornamentals. Lavender is exceptional for honeybees and bumblebees. Sedum is critical as a late-season nectar source when most other flowers have finished. Coral bells attracts hummingbirds specifically. For a deep dive into building a pollinator-focused garden, see our bee and pollinator garden guide.
Can I grow perennials in pots or containers?
Yes, but containers require more management than in-ground plantings. The main challenge is overwintering — container roots are exposed to temperature extremes that in-ground roots are insulated from. In Zone 5 and colder, move containers to an unheated garage or shed for winter, or choose varieties rated two zones colder than your zone (so a Zone 5 gardener plants Zone 3-rated varieties in containers). Hostas, coral bells, and daylilies all do well in containers with adequate pot size (at least 30 cm / 12 in diameter per plant). Lavender thrives in terracotta pots with excellent drainage. Echinacea develops a deep taproot and prefers in-ground planting.
Is echinacea actually medicinal, or is that marketing?
Echinacea has genuine clinical support for modest immune benefits — multiple randomized controlled trials have shown statistically significant reductions in the severity and duration of upper respiratory infections, particularly when preparations are taken early in symptom onset. The evidence is stronger for root preparations than aerial parts. The most commonly studied species is Echinacea purpurea, which is also the most garden-worthy for ornamental use. The medicinal and ornamental applications are the same plant — growing echinacea in your garden gives you both a beautiful border plant and a harvestable medicinal herb. Learn more in our echinacea growing guide.
What perennials grow well in full shade?
From this list, hostas are the clear champion for deep shade — they’re one of very few perennials that not only tolerate full shade but thrive in it. Coral bells handles part to full shade well, especially in warmer climates where it appreciates protection from afternoon sun. All other plants on this list prefer sun and will produce fewer flowers in shade. For a broader shade garden, pair hostas with astilbe, ferns, bleeding heart, and coral bells — these all share the same growing conditions and create a layered, textural planting that looks good all season with minimal maintenance.
How do I save seeds from perennial flowers?
Most open-pollinated and heirloom perennials produce seeds that grow true to type and can be saved easily. Allow a few flowers to fully set seed — the seed head should be dry and brown before harvest. Cut the seed heads and spread them on a screen or paper to dry for 1–2 weeks, then thresh and store in a labelled paper envelope in a cool, dry place. Echinacea, yarrow, shasta daisy, and black-eyed susan all save easily this way. Daylily and peony seeds are viable but produce plants quite different from the parent — results are variable and blooms take years. Named cultivars of coral bells and hostas are often hybrids and won’t breed true from seed.
Are any of these perennials toxic to dogs or cats?
Hostas are toxic to both dogs and cats — ingestion causes vomiting, diarrhea, and lethargy. Daylilies (Hemerocallis) are extremely toxic to cats specifically, causing acute kidney failure even from small amounts of pollen or plant material. Yarrow can cause vomiting and excessive salivation in dogs and cats if ingested in quantity. Echinacea, shasta daisy, and black-eyed susan are generally considered non-toxic, though any plant can cause digestive upset if eaten in large amounts. If you have cats that spend time outdoors, avoid daylilies entirely — the risk is serious. When in doubt, consult the ASPCA Animal Poison Control database for the most current information.
Which perennials have the longest bloom time?
Yarrow, shasta daisy, and black-eyed susan all have bloom windows of 10–14 weeks under good conditions — especially when the first flush is deadheaded to encourage a second. Echinacea also has a long individual bloom window per flower. Daylilies have one of the shortest individual flower lifespans (one day per flower) but the plant as a whole blooms for 4–6 weeks because flowers open sequentially. Peonies have the shortest bloom window on this list — a spectacular 2–3 weeks — but their other virtues (fragrance, longevity, cold-hardiness) more than compensate.
What perennials work best for a cut flower garden?
Shasta daisy is the strongest cut flower on this list — long stems, classic look, and harvesting actually promotes more blooms. Echinacea makes beautiful, long-lasting cuts with distinctive seed heads that dry well. Lavender is excellent for both fresh bouquets and drying — harvest just before the flowers fully open for the best scent and colour retention. Yarrow is outstanding dried, holding its colour and shape for months. Peony is the most spectacular cut flower of the group, though the bloom window is short. Avoid cutting daylilies — individual flowers last only one day in a vase.
How far apart should I plant perennials?
Spacing varies significantly by plant size, but the general principle is to plant at a distance equal to half the mature spread. For the plants on this list: echinacea and black-eyed susan at 45–60 cm (18–24 in); daylilies at 45–60 cm (18–24 in); lavender at 45–60 cm (18–24 in) for good airflow; yarrow at 45–60 cm (18–24 in) to reduce mildew; sedum at 45 cm (18 in); shasta daisy at 30–45 cm (12–18 in); coral bells at 30–45 cm (12–18 in); peonies at 90–120 cm (36–48 in) — they dislike being moved; hostas from 30 cm (12 in) for small varieties to 90 cm (36 in) for large ones. The garden looks sparse in year one; resist the urge to over-plant, as crowded perennials produce fewer flowers and more disease.
Do I need to water established perennials?
After the first full growing season, most perennials on this list are quite drought-tolerant and rarely need supplemental watering in climates with average rainfall. Yarrow, sedum, lavender, and echinacea are the most drought-tolerant — in many climates they thrive on rainfall alone after the first year. Hostas, coral bells, and shasta daisy prefer consistent moisture and may need watering during extended dry spells. The first season is critical for all of them: deep, infrequent watering (once or twice a week, soaking to 15–20 cm / 6–8 in depth) encourages roots to go deep, which is what creates true drought tolerance in subsequent years. Shallow, frequent watering produces shallow roots and permanently water-dependent plants.
Are there low-maintenance perennials that also have edible or medicinal uses?
Several plants on this list double as useful medicinal or culinary herbs. Echinacea root and flowers are widely used in immune-support preparations — the same plant you’re growing for ornament can be harvested from. Lavender flowers are culinary-grade in many varieties — English lavender (Lavandula angustifolia) specifically is used in baking, teas, and cocktails. Yarrow has a long history of topical use for wound care and as a tea for fever support. Daylily buds and flowers are edible (used in Chinese cooking as “golden needles”) though related plants in the genus can cause issues for cats. Growing plants with dual ornamental and functional value is one of the smartest moves a low-maintenance gardener can make — the garden earns its space in multiple ways at once.
