Siberian squills through the year
Against the frost risk in Taza
Why these dates
Plant in early autumn, 7cm deep, in generous drifts - a handful of squills is invisible. Self-seeds freely once settled, so put them where spread is an advantage rather than a problem.
Hardy to about -35C, further north than almost any other spring bulb. Requires a genuinely cold winter and does not persist below zone 8.
Siberian squills 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 Taza instead of forwards from its start.
Taza sits in zone 9b, 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 297 days, against 120 to 160 days to first flower for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
