Why these dates

Soak the tubers overnight before planting - they arrive bone dry and dehydrated tubers frequently fail. Plant 5cm deep in early autumn, any way up; the growing point is impossible to identify and the tuber sorts itself out.

Hardy to about -20C. Flowers early enough that a hard frost sometimes catches open blooms, which recover. Goes fully dormant by midsummer and tolerates dry summer shade better than most spring bulbs.

Grecian windflowers are anchored to the first autumn frost rather than the last spring one, so the planting window on this page counts backwards from the end of the season in Khemisset instead of forwards from its start.

Khemisset sits in zone 10b, which is milder than this crop wants, and a winter that never really arrives is its own problem. The dates below still describe the right time of year; the open question is survival rather than timing.
