(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

A seldom-seen annual or short-lived perennial, this easy-to-grow plant performs as the perfect filler in beds and containers. It forms a well-branched compact mound of deeply lobed, dark green leaves, which provide an interesting textural backdrop to its charming, hibiscus-type flowers. The flowers are truly stunning with their cream petals, purple-hued undersides, and deep burgundy centers. While each flower lasts only a single day, the plant blooms profusely all season and produces inflated seedpods. The flowers will not normally open on a cloudy day, but this is a small price to pay for such a gem of a plant.
