Harvest anemones as they ripen
Don't tug. Use scissors or pruners for clean cuts — torn stems invite disease.
Poppy anemones (Anemone coronaria) produce vivid, poppy-like flowers with striking black centers, in shades of red, blue, purple, white, and bicolor. A cool-season cut flower favorite, they thrive in the mild overlap between winter's end and summer's arrival. In mild-winter zones (7+), fall planting yields a spectacular mid-spring bloom flush that florists prize. In colder zones, spring planting produces summer flowers. The 'Meron' and 'Moissonnier' series dominate commercial cut flower production; 'De Caen' and 'St. Brigid' are standard home garden strains.

Anemones Heat Requirements (GDD)
What are Growing Degree Days (GDD)?
Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.
Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

Growing Tips for Anemones in DeKalb County
Direct sow Anemones outdoors after April 22 in DeKalb County when soil has warmed and frost danger has passed.
General growing tips
Soak corms in tepid water for 2–4 hours before planting to rehydrate them. Plant 2–3 inches deep with the flat or rough side down (corms are irregular). Space 4–6 inches apart. Anemones are cool-season plants — they need cool temperatures to set buds; summer heat causes dormancy. In zones 7+, fall planting allows corms to root through winter and bloom in March–April. In zones 5–6, start corms indoors 4 weeks before last frost, then transplant after danger of hard freeze passes. In zones 9–10b, plant from October through January for a succession of blooms. After bloom, allow foliage to die back; corms can be lifted, dried, and stored in a cool, dry place through summer.
