Dr. Ralph (Herb) and Dorothy Benedict of Michigan registered this
self-pollinated seedling of H. 'Beatrice' in 1995. It
forms a small size mound 6 inches high by 17 inches wide with elliptic
shaped leaves. In August, it bears white flowers.
The Hostapedia by Mark Zilis (2009), "...'White Dove' and 'White Swan' sported out of the same selfed 'Beatrice' seedling."
