Persicaria polymorpha

Description

This massive herbaceous shrub needs a lot of room to show off its vase-shaped form, but it does not spread or self-sow like some of its relatives. It blooms from June and continues throughout the summer atop 6 foot tall stems. The large, white, astilbe-like blossoms fade to pink and then reddish-brown as the season comes to a close.

Easily grown in average, medium, well-drained soils in full sun. Prefers moist soils but can tolerate some shade and dry conditions. Tolerant of heat, humidity and, once established, some drought.
