Plant Breeder’s Rights:



Showy 2-inch (5 cm) clusters of ball-shaped, red buds are cradled in soft, silvery foliage. They open to starry white flowers with prominent yellow centers and the genus’ distinctive stiff, papery texture, gradually fading to a soft oatmeal hue. Foliage is attractive all summer, especially if given a light shearing after flowering. Blooms May through June in the US; March through May in the UK. With most plants, gardeners eagerly await the opening of the buds into their final, full-flowered form. Not so in the case of ‘Ruby Cluster’, whose buds are as attractive and interesting as the flowers they will become – perhaps even more so. Though not hardy in much of North America, it is evergreen in areas mild enough to enjoy it for more than one season. Elsewhere, this is a marvelous annual and a choice container candidate, forming a tidy, uniform mound of silvery leaves. Comes to Must Have Perennials from English gardener Chris Bowyer.
