Growing flowers in Zone 7
Zone 7 supports a classic, layered flower garden — spring bulbs, summer perennials like coneflowers and peonies, and a long run of annuals. Most cottage-garden favorites are hardy here, returning year after year.
The flowers below are popular, dependable picks — but since many are perennial, always confirm a variety is rated hardy to Zone 7 before planting, so it survives the winter (last frost around Late March – mid April).
Flowering plants serve the garden in multiple roles: ornamental colour, pollinator support, and cut flower production. Annual flowers bloom for a single season and are replaced; perennial flowers return year after year once established. Understanding the distinction — and your zone's winter hardiness limits — is essential to building a lasting flower garden.
