Zone 8 questions
What does USDA Zone 8 mean?
Zone 8 averages winter minimums of 10°F to 20°F. A plant rated for Zone 8 survives those lows in the ground — mild winters open the door to broadleaf evergreens and early bloom.
When is the last frost in Zone 8?
Typically around late March, with first fall frost near mid-November. Local microclimates shift this by a week or two — Sow tracks your actual forecast and warns you before frost nights.
How many plants grow in Zone 8?
9,952 plants in the Sow catalog are hardy in Zone 8, from groundcovers to shade trees. The picks above are ranked by real gardener saves, not editorial guesswork.
