Quick Grow Facts

• Plant type: Cool-season perennial vegetable; annual or biennial treatment is practical where frost, heat or wet soil prevents reliable crowns
• Scientific name: Cynara cardunculus Scolymus Group (widely listed as Cynara scolymus)
• Variety: Violet de Provence
• Seed form: 20 g raw seed; raw describes form and does not prove untreated status
• Packet sowing season: Spring/Summer; use the linked regional guide to place the crop into a safe cool establishment window
• Position: Full sun in cool weather; protect establishing plants from severe dry heat and wind
• Sow depth: About 5 mm; cover the seed and give bright light immediately after emergence
• Germination light: Cover the seed; give bright light immediately after emergence
• Germination temperature: 18–20°C
• Germination: Packet planning window 14–21 days under steady moisture and warmth
• Transplant: At 3–4 true leaves, usually about 8–10 weeks; harden for 7–10 days and do not bury the crown
• Chilling for buds: Established 4–6-leaf seedlings commonly need about 250–500 or more hours below 10°C, depending on cultivar; a practical minimum treatment is about 10 days at 7–10°C without freezing
• Spacing: 1 m minimum; allow about 1.2 m for permanent plants where space permits
• Height and spread: Commonly about 1–1.5 m high and wide under good conditions
• Harvest: Packet 80–100 days is an optimistic early-crop line; practical annual planning is about 4–6 months from transplant, with stronger harvests often after establishment
• Bud outcome: Expect tapered violet-and-green buds, harvested young and tight. Head size, colour uniformity and whether the supplied lot is hybrid or open-pollinated are not confirmed.

Sowing and Care

Sow about 5 mm deep at 18–20°C in a deep cell or 8–10 cm pot of clean, free-draining seedling mix; do not surface-sow. Keep it evenly moist but never saturated and provide bright light from emergence. Transplant at 3–4 true leaves before roots coil.

For first-year bud set, established seedlings need cool exposure; seed refrigeration is not a universal substitute. Plant into deep, compost-enriched, well-drained soil at least 1 m apart. Keep water steady through bud formation, feed moderately during active growth, and keep wet mulch away from the crown.

Harvest

Cut the primary bud first while the bracts are tight, leaving about 7.5–10 cm of stem. Pick smaller side buds as they size up. Open flowers are beautiful, but the bud becomes fibrous and past eating quality once the scales spread.

Safety

Never eat the seed or use it for sprouting. Use only controls currently labelled in South Africa for edible artichoke and observe all withholding periods.
