plant sale text: The blooms of crimson-eyed rose-mallow are among the largest of any of our native perennials. This shrubby perennial has plump, conspicuous flower buds - marvels of architecture and design in their own right which cluster at the tip of each stem and open several at a time. Crimson-eyed rose-mallow normally grows in wet areas such as in marshes and along shorelines, though this perennial also thrives in garden soils with average moisture. 1997 N.C.

comments:

cultural notes: Crimson-eyed rose-mallow is a native perennial that occurs in open swamps and fresh and brackish marshes. Full sun and good air circulation are necessary for optimum blooms and disease suppression. Unfortunately its creamy-white, crimson-throated flowers are a favorite food of the Japanese beetle. The blossoms create a showy display throughout the summer, but as with other Hibiscus, each flower lasts for just one day.
