Grecian windflowers through the year
Against the frost risk in Nador
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 Nador instead of forwards from its start.
Nador sits in zone 10a, 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.
The median frost-free season here is 303 days, against 140 to 180 days to first flower for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
