Red Express Cabbage Seeds

Red Express Cabbage — Vivid, Fast-Maturing & Reliable in Short Seasons

Red Express is one of the fastest-maturing red cabbage varieties available — at just 63 days from transplant, it reaches a compact, tight 1–1.5 kg (2–3 lb) head that’s ideal for home kitchen use. Standard red cabbages often require 75–85 days or more, which makes them a challenge in shorter growing seasons across the northern US and Canada alike. Red Express cuts that window significantly without sacrificing the deep burgundy-purple colour, crisp texture, and mildly sweet, slightly peppery flavour that makes red cabbage so versatile. The compact head size is also practical — unlike the enormous heads that storage-type cabbages produce, Red Express makes a quantity you can actually use without waste.

The colour of red cabbage is pH-dependent — it turns blue-purple in alkaline conditions and bright red-pink in acidic ones. This chemistry is part of what makes red cabbage so useful in the kitchen: adding a splash of vinegar or lemon juice when cooking instantly brightens the colour from dull purple to vivid magenta. Pickled red cabbage turns a stunning hot pink within hours, making it one of the most visually striking condiments you can make from your garden.

Starting Red Express Cabbage from Seed

Start indoors 4–6 weeks before your last frost date for spring planting, or direct sow in midsummer for fall production. Sow ¼ inch deep and maintain temperatures of 15–21°C (60–70°F) for germination — cabbage germinates readily in cool conditions. Transplant outdoors 2–4 weeks before your last frost date; cabbage is frost-hardy and young transplants tolerate temperatures as low as -5°C (23°F) with light protection. Harden off seedlings gradually before transplanting. For the complete sowing, spacing, pest-prevention and harvest walkthrough, see our complete guide to growing cabbage from seed.

For a fall crop — which often produces the best-flavoured cabbage — direct sow or transplant in midsummer so heads mature in cooling fall temperatures. Frost after head formation actually improves flavour, converting some starches to sugars. To keep cabbage moths off the developing heads, interplant the aromatic herbs and flowers in our vegetable companion planting chart.

Soil, Care, and Watering

Cabbage thrives in fertile, well-draining soil with consistent moisture and a pH of 6.5–7.0. Amend beds with compost before planting and apply a nitrogen-rich fertilizer early in the growing season to promote leafy growth. As heads begin to form, reduce nitrogen and maintain consistent watering — irregular moisture during head development causes heads to split. Space transplants 45–60 cm (18–24 in) apart; crowded cabbages produce smaller, less dense heads. Row cover at transplanting deters cabbage loopers, root maggots, and other early-season pests.

Harvesting

Red Express heads are ready when they feel solid and firm when squeezed — a loose or spongy feel means the head needs more time. Cut at the base with a sharp knife. If you leave the root and outer leaves in place, small secondary heads often sprout from the base — a bonus harvest of smaller, tender cabbages 4–6 weeks later. Red cabbage stores well in the refrigerator for 3–4 weeks whole, or months in a cold room near 0°C (32°F).

Saving Seeds from Red Express Cabbage

Cabbage is a biennial — it flowers in its second year after overwintering. In Zones 6 and warmer, plants can overwinter in the ground. In colder zones, dig up the root ball, store in barely damp sand at near-freezing temperatures, and replant in spring. Cabbage cross-pollinates via insects with other Brassica oleracea varieties (broccoli, kale, Brussels sprouts, kohlrabi, cauliflower) — isolate by 300+ metres for pure seed. Seed pods shatter when ripe; collect pods when yellowing and dry indoors before threshing. Viability holds 4–5 years. Our complete seed-saving guide covers the biennial process in detail.
