The story
Ninebark is named for bark that peels away in layer after layer, supposedly nine of them. It grows on stream banks and rocky slopes across the north and east, and it is about as tough as a shrub gets.
Planting
Sun or part shade, in almost any soil: clay, rock, wet or dry.
Growing
Cut a third of the oldest stems to the ground each winter to keep it fresh. That is all.
Harvest and use
White flower clusters in June for small native bees, red seed capsules after, and dense cover where songbirds nest.
What to watch for
Powdery mildew on some purple-leaved varieties. The plain green native rarely bothers.
