Flowers from the second year, on plants 40–46" tall. Open-pollinated.

Growing Information

Days to germination

About 7–10 days at 22–24°C (72–75°F).

Starting indoors

Recommended. Sow 10–16 weeks ahead of transplanting, uncovered, since light is needed; water from below or mist. Move seedlings to cell packs or 2–4" pots 5–8 weeks after they emerge. Harden off and plant out once the last frost has passed.

Growing on

Grow seedlings at 13–16°C (55–60°F), and keep them below about 21°C (70°F).

Plant spacing

18–24". Clumps spread slowly and can be left in place for years.

Soil

Dry, sandy soil; tolerates salty ground. Easily harmed by overwatering.

Light

Full sun.

Harvest

Cut when the whole head and its bracts have turned blue or white, depending on variety. Hang to dry, or use a desiccant to keep more color.

Uses

Fresh and dried flowers; the middle of a perennial border. Also called sea holly.
