Echinacea - Key Growing Information
DAYS TO GERMINATION:
Allow 10–15 days at 65–70°F (18–21°C).
SOWING:
Transplants are recommended: sow 8–10 weeks before planting out. Move seedlings into cell packs or larger containers once the first true leaves appear, about 30–40 days after sowing, then harden off and plant outside in late spring or early summer.
DIRECT SEED:
In spring, sow once the soil is warm, about 65°F (18°C), in groups of 3–4 seeds 1/8" deep, thinning to one plant. A fall sowing lets winter's temperature swings and natural moisture trigger germination.
LIGHT PREFERENCE:
Full sun, with some tolerance for part shade.
SOIL REQUIREMENTS:
Ordinary soil with good drainage.
PLANT SPACING:
18–24" apart. Divide only when clumps become crowded.
HARDINESS ZONES:
Hardy in Zones 3–10.HARVEST: For fresh flowers, cut while the petals are still unfurling. For fresh cones, cut once the center has domed up and turned golden. For dried flowers or cones, strip the petals and hang stems to dry.
USES:
Cut flowers, plus seed heads for fresh or dried use. Good in beds, borders, massed plantings and wildflower meadows.
