Winter aconites through the year
Against the frost risk in Kayseri
Why these dates
Plant dry tubers as early in autumn as you can get them, 5cm deep, after an overnight soak. Expect a proportion to fail regardless. The reliable method is to beg a clump from an established planting just after flowering and plant it in leaf.
Hardy to -30C and flowers in midwinter, opening whenever the temperature rises above about 10C and closing again. Needs cold winters and cool summers; useless in a hot climate.
Winter aconites 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 Kayseri instead of forwards from its start.
Hardiness is not the obstacle here. Kayseri is zone 7a, 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 179 days, against 100 to 150 days to first flower for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
