Why these dates

Start indoors twelve weeks before the last frost and plant out four weeks before it, or sow in midsummer for autumn planting and winter flowers. Shear back by half in midsummer if it looks exhausted and it will recover for autumn.

Hardy to about -18C, more so than the pansy, and flowers through mild winters. Handles summer heat slightly better too, though it still pauses in the hottest weeks.

Seed packets and extension guides express timing as weeks either side of the last spring frost, because that is the only reference point that travels. Violas are timed from 12 weeks before that frost for an indoor start, with planting out 4 weeks before it, and this page simply resolves those offsets against the frost date computed for Luhansk.

Hardiness is not the obstacle here. Luhansk is zone 5b, 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 176 days, against 85 to 110 days to first flower for this crop counted from planting out. That margin is what decides whether a late sowing is worth attempting.
