Growing flowers in Zone 2

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.
