Days To Maturity
Days To Maturity
Average number of days from seeding date to harvest, within a specific crop group. If a transplanted crop: average number of days from transplant date. Not sure if crop is direct-seeded or transplanted? Check the Growing Information box for details. If crop can be both direct-seeded or transplanted, days to maturity refers to direct seeding. Days to maturity for all flowers and herbs is calculated from seeding date.

Life Cycle
Plants can be Annuals (single growing season), Perennials (grow year after year), Tender Perennials (grow year after year in warmer climates; and in some cases when given special protection in colder climates), or Biennials (require two years to mature).

Imperial Star Artichoke Seed
Early green annual for summer harvests.
A green artichoke specifically bred for annual production, Imperial Star will produce well-developed artichokes the first year from seed. Plants become 1 1/2–3' tall and have an open growth habit. Each typically produces 1–2 primary buds, which average 3–4" in diameter, and 5–7 smaller secondary buds. Perennial in Zone 7 and warmer; otherwise treat as an annual.Specs:

SCIENTIFIC NAME:
Cynara cardunculus var. scolymusCULTURE:
Artichokes require very fertile, well-drained soils with a pH of 6.5–7.0. Sow artichokes indoors 8–12 weeks before transplant date. Plant 2–3 seeds ¼" deep, per cell in 50-cell trays or individual containers. Germinate at 70–80°F (21–26°C) and grow at 60–70°F (15–21°C) day and 50–60°F (10–15°C) night. Thin to 1 plant per cell or container. Transplant 6- to 12-week-old plants to the field 2–3' apart in rows 3–6' apart. Protect from frost.DAYS TO MATURITY:
From date of transplant.IMPORTANT COLD TREATMENT (VERNALIZATION):
Artichokes need 10 days of 45–50°F (7.2–10°C) temperatures to induce budding. In mild regions this can be accomplished naturally when overwintering a fall-planted crop. For spring-planted crops, cold exposure can occur in a refrigerator or cooler. Timing transplanting to expose seedlings to these temperatures is possible but may be unreliable.MILD AREAS:
Where winter low is above 14°F (-10°C), sow seeds in fall, harvest in spring.HARVEST:
Clip buds at desired size before bracts fully open.SEEDS/LB. (AVG.): 11,500.PACKET:
