Imperial Star Artichoke Seed
About this variety
A green artichoke that crops in year one.
Imperial Star was bred to produce well-formed buds the first year from seed. Open plants 1½–3' tall usually give 1–2 main buds averaging 3–4" across, followed by 5–7 smaller side buds.
It comes back each year where winters stay mild (about Zone 7 and up); in colder gardens treat it as an annual.
About 85 days from transplanting. Open-pollinated.

Growing Information
Scientific name
Cynara cardunculus var. scolymus
Soil
Artichokes need very fertile, free-draining soil at pH 6.5–7.0.
Starting indoors
Start 8–12 weeks before planting out. Sow 1/4" deep, 2–3 seeds to each cell of a 50-cell tray or small pot, and thin to the strongest seedling. Germinate at 21–26°C (70–80°F), then grow on at 15–21°C (60–70°F) by day and 10–15°C (50–60°F) at night.
Transplanting
Set out plants 6–12 weeks old, 2–3' apart with 3–6' between rows, and protect them from frost.
Days to maturity
Counted from transplanting.
Cold treatment
Plants must spend about 10 days at 7–10°C (45–50°F) before they will set buds. A fall-planted crop gets this naturally over a mild winter. For spring planting, chill the young plants in a cooler or refrigerator; trying to time the cold outdoors is possible but less dependable.
Mild-winter areas
Where winter lows stay above about 14°F (-10°C), sow in fall for a spring harvest.
Harvest
Cut buds at the size you want, before the bracts start to spread open.
