Persian buttercups through the year
Against the frost risk in Rabat
Why these dates
Where winters stay above about -7C, plant in autumn for spring flowers - this gives much the better crop. In colder gardens, start the corms indoors in late winter and plant out around the last frost, or grow them in a cold frame. Soak the claws for three or four hours before planting, points downward, 5cm deep.
Hardy only to about -7C, so autumn planting is limited to zone 8 and warmer. The foliage takes a light frost; a hard one kills the plant. It also stops flowering in real heat, so a hot spring simply ends the season early.
Persian buttercups 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 Rabat instead of forwards from its start.
Rabat sits in zone 11b, 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.
