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 Ankara instead of forwards from its start.

Hardiness is not the obstacle here. Ankara is zone 7b, comfortably inside the range this crop is rated for, so an established plant should come through an average winter without protection.

The median frost-free season here is 185 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.
