Summerific® Valentine's Crush™ Rose Mallow

Hibiscus ‘Valentine’s Crush’ is a hardy herbaceous hybrid rose mallow in the Summerific collection, selected for upright, sturdy growth and bright cherry-red flowers. Its broad, flat blooms open about 7–8 inches across, with a dark red eye, and flower from late July into early September. ## Garden Use Use this late-season perennial in a sunny border or as a focal plant where its large flowers can be seen. It grows upright with strong, well-branched stems and dark-green, variably lobed leaves that take on a bronze cast in full sun. The Walters Gardens profile lists a mature height of about 5 feet and spread of about 3.5 feet, with hardiness in USDA zones 4–9. Full sun or part shade suits it; moist, well-drained soil and steady watering support flowering and lush foliage.

Hibiscus emerges later than many perennials in spring, so wait for new growth before cutting back the previous season’s stems. Keep soil consistently moist during active growth, and remove spent flowers when you want a tidier display. Walters Gardens notes that Japanese beetles may feed on hardy hibiscus.
