Anemone: Sowing, planting and harvest calendar
When and how do you sow anemones outdoors?
Identify the anemone before sowing: small spring species, florist's anemones and autumn anemones do not all follow the same cycle. Check that you have seeds, not small dry tubers intended for planting. Sowing season and temperature requirements depend on the species. Spring is not one common rule for every anemone.
To monitor germination, sow thinly in a pot or tray with drainage holes and a fine, free-draining medium. Cover at the depth recommended for the seed lot, then water gently. Add a label with identity and date. Some seeds benefit from fresh sowing, while others may need a sequence of temperatures including a cold, moist phase.
Place the container outdoors in a suitable seedling position, protected from heavy rain and drying. Maintain moisture without leaving water in a saucer. Do not discard a pot too soon because it shows no shoots: emergence can be slow or staggered. Once seedlings are sufficiently developed, transplant gently while preserving their roots. Eventual spacing and exposure depend on the group. A young seed-grown anemone does not necessarily flower in its first season.
