Notes: Ninebark is a fairly common garden shrub that is attractive while in flower and good for wildlife. It is native to Ontario and most of the eastern half of North America. It is generally found close to water but it is a versatile plant that can be grown in a wide range of conditions.

This shrub flowers for a few weeks in June and is ladened with domed clusters of flowers that bees really like. When not in flower, this shrub will go unnoticed unless you buy some of the cultivars that have been bred to make the leaves more interesting; however, when you buy such cultivars, the leaf chemistry has been changed in these plants in ways that may affect their wildlife value.

The buds form on new wood so any pruning should be done immediately after flowering. The seeds that formed are eaten by birds in August.
