Perennial Hibiscus plants can add a touch of the tropics to your flowering beds or butterfly gardens. With darker leaf foliage and buds that open to huge blooms all along the stems instead of just at the top, these beauties are sure to brighten your late Spring to early Fall gardens while attracting pollinators. Remove spent blooms to encourage new buds to open. These varieties love the sunny and more moist conditions, but can thrive in drier soils as well as long as they receive regular weekly watering.
