Quick Overview:

Deep, bluish-green, leathery foliage and 14” pure white wide lace cap blooms make for a stunning combination in any setting. This beautiful native selection stands tall and never flops, even with its massive blooms. It’s an upright, yet bushy plant that will stop anyone walking past with the display of truly incredible blooms and stout and sturdy stature.  Reportedly much more heat and drought tolerant than other arborescens varieties such as ‘Annabelle.’

Easily grown in average, medium moisture, well-drained soils in part shade.  Plants may die to the ground in harsh winters. Bloom occurs on new wood, so plants may be pruned back close to the ground in late winter to revitalize and to encourage vigorous stem growth and best form. If not pruned back, any weakened and/or damaged stems should be removed in early spring.
