Althea 'Ardens' (Rose of Sharon)

Hibiscus syriacus 'Ardens' is a classic Rose of Sharon prized for its stunning double purple-lavender blooms that smother the plant from midsummer through fall — long after most other shrubs have finished flowering. The upright, vase-shaped form makes it ideal for tight spaces, hedges, or as a vertical accent in the landscape.
