Bright green foliage with graceful racemes of white heart-shaped flowers. Slightly less robust than the species. Deciduous. Attractive to butterflies and hummingbirds. Deer resistant.
Prefers partial to full shade and evenly moist, well-drained, organic-rich soil.
Since foliage is dormant in summer, Astilbes, Ferns, Hostas, and Arum are excellent companion plants.
