How to read the zone range

A plant listed for zones 4 to 8 survives the average winter in zones 4 through 8. North of that range the roots freeze; south of it, many need more winter chill than they get or struggle with hot humid nights. Plant in spring after the soil can be worked, or in early fall at least six weeks before the ground freezes so the roots settle in.

Hardiness ranges, light and size are typical figures from university extension services and botanic garden plant records; a named variety can differ, so check its tag. Planting dates come from each zone's median frost dates (NOAA 1991 to 2020 climate normals) and the timing rules in how we check.
