Gauras through the year
Against the frost risk in Kayseri
Why these dates
Plant out after the last frost in the sunniest, best-drained position available. Cut back to 20cm in spring rather than autumn. In cold gardens treat it as a short-lived plant and expect to replace it every three or four years.
Hardy to about -12C in dry soil and much less where winters are wet, which is what limits it far more than absolute cold. Flowers through light autumn frosts.
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. Gauras are timed with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Kayseri.
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.
Do not expect a crop in the first year. A plant set out now should give its first worthwhile pick around year 1, and will then produce every year after that, which is what makes the planting decision worth getting right the first time.
