Red Sprouting Early

Brassica oleracea var. italica

vegetable

Red Sprouting Early is a purple-headed broccoli variety that produces multiple smaller florets rather than one large central head. It's an early-maturing cold-hardy brassica that thrives in cool seasons and develops deep purple to wine-red coloring as temperatures drop.

Growth Stages

1

Seedling

2-3 weeks

Cotyledons emerge; true leaves develop with characteristic brassica serrated edges

Keep soil consistently moist. Provide bright light to prevent leggy growth. Maintain temperatures 60-70°F. Thin seedlings to strongest plant if direct seeding.

2

Vegetative/Transplant

3-4 weeks before field planting

Plant develops 4-6 true leaves; sturdy stem and expanded leaf canopy

Harden off transplants gradually before planting out. Plant in cool season (spring or fall). Avoid transplanting during extreme heat. Side-dress with compost at planting.

3

Rosette Development

3-4 weeks

Plant forms robust basal foliage with tight leaf arrangement; dark blue-green color

Maintain consistent watering. Apply organic mulch around base. Feed with balanced fertilizer (10-10-10) every 3 weeks. Remove yellowing outer leaves. Monitor for pests.

4

Sprouting & Heading

2-3 weeks

Purple floret clusters emerge from leaf axils along main stem; central head forms first, then lateral sprouts develop

Harvest central head when fully formed but before opening. Cool weather enhances purple coloring—night temperatures below 50°F deepen color. Continue watering deeply.

5

Harvest & Regrowth

4-6 weeks of continued harvest

Multiple side shoots continue producing smaller purple heads; plant extends harvest season

Cut central head 6-8 inches from base with sharp knife. Lateral sprouts will develop over following 4-6 weeks. Continue watering and feeding. Harvest shoots regularly to encourage more production.

Common Pests

  • Install row covers or netting over young plants. Hand-pick caterpillars. Apply Bt (Bacillus thuringiensis) spray every 7-10 days. Interplant with herbs like dill and chamomile.

  • Use reflective mulches and row covers. Spray neem oil or kaolin clay on foliage. Maintain plant vigor with adequate water and fertility. Vacuum beetles with handheld device.

  • Strong water spray to dislodge. Insecticidal soap for heavy infestations. Encourage beneficial insects like ladybugs. Neem oil applications every 10-14 days.

  • Apply Bt spray. Hand-pick larger caterpillars. Row covers on young plants. Maintain clean garden to eliminate hiding spots.

  • Rotate brassicas off site 4+ years. Improve soil drainage. Raise pH to 7.0+ with lime. Solarize soil in infected areas. Choose resistant varieties when possible.

Uses

🍳

Fresh eating and cooking

Culinary

Red Sprouting Early develops a sweeter, milder flavor than standard broccoli, especially after frost. The purple florets and tender stems are excellent steamed, roasted, or eaten raw. [source]

🍳

Ornamental food garden

Culinary

The striking deep purple color makes Red Sprouting Early an attractive edible landscape plant. The successive sprouting habit provides visual interest and prolonged harvest. [source]

💊

Cruciferous vegetable nutrition

Medicinal

Like all brassicas, Red Sprouting Early contains sulforaphane and other glucosinolates with potential cancer-preventive properties. Rich in vitamin C, K, and fiber. [source]

🏠

Winter food production

Household

As a cold-hardy variety, Red Sprouting Early extends the growing season into fall and early winter in most climates, providing fresh produce when other crops have finished. [source]

🦋

Pollinator support

Wildlife

If allowed to bolt and flower, the yellow broccoli flowers attract bees and other beneficial pollinators, supporting garden ecosystem health. [source]

Harvest Tips

Harvest the central head when florets are tightly clustered and deep purple before any flowers open (usually 50-70 days from transplant). Cut 6-8 inches below the head with a clean, sharp knife. Lateral sprouting heads develop within 2-3 weeks and can be harvested continuously for 4-6 weeks. Best flavor develops after light frosts; cold weather enhances sweetness and purple coloring. Harvest in early morning when plants are fully hydrated.

Fun Facts

  • 🌱 Red Sprouting Early is particularly cold-hardy and actually improves in flavor after experiencing frost, as the plant converts starches to sugars as an antifreeze mechanism.
  • 🌱 Unlike standard broccoli that produces one large head, this variety continues producing multiple smaller purple heads from lateral buds for 6+ weeks, making it economical for both home and market gardeners.
  • 🌱 The deep purple pigmentation comes from anthocyanins, the same antioxidants found in blueberries and red wine, which develop more intensely in cooler temperatures.
