Extremely rare is this variegated variety, albeit irregular. At first we though it reverts on a whim and watched it over the last 5 years. Results: it hasn't reverted, but naturally has lots of green leafs. Bears classic white flowers like the straight species. Spreading, easy to grow "filler" for the woodland garden or in front of a shady border. Prefers moist, humusy soil but tolerates drier soil in summer as they are then dormant.
