Description

Hibiscus moscheutos (Rose mallow). This species produces large constant blooms in the summer. The flowers will only last one day, but are continuous throughout late summer until the first autumn frost. The foliage is deep green with large and heart-shaped leaves. The Rose Mallow requires constantly moist soil and will not tolerate dry conditions. Prefers full sun but will need partial shade in hot, humid climates. For the biggest flowers try 'Super Giant'.
