Plum Crazy Rosemallow, Rosemallow

Hibiscus moscheutos ‘Plum Crazy’ is a striking herbaceous perennial valued for its huge magenta-plum flowers and dramatic late-summer display. It forms a sturdy, upright clump of rich green foliage that emerges late in spring. In mid to late summer, enormous tropical-looking blooms—often 8–10 inches across—open in vibrant magenta-purple to plum tones with a darker central eye, creating a bold focal point in the garden. The flowers continue for weeks and attract many pollinators.
