Ninebark ‘Summerwine’ | Plant Profile

Ninebark 'Summerwine' (Physocarpus opulifolius) are mound forming deciduous shrubs. The foliage is deeply cut, making each branch seem like it's own arm from the base of the plant. The foliage is erect at the base but droops back to the ground with length, creating a fountain-like appearance. The foliage is a deep merlot color that is complemented by small white flowers that dot nearly the entire plant. The foliage may become greenish in the hottest months of summer. The bark on these shrubs is exfoliating, meaning the dark bark peels in strips which reveals light colored bark beneath. These plants bring multiseason interest as the bark is quite showy, but is hidden in the winter. When leaves drop in winter, the interesting bark is revealed.

Ninebark 'Summerwine' are hardy to the Pittsburgh area, tolerating a wide range of soils. They are capable of growing in rocky, dry soils and clay. Soils should be dry to medium moisture, but they are quite tolerant of drought. Full sun is best, but some shade can be appreciated in the hot summer months. In winter, foliage should be cut to the ground to promote growth in the spring.

These hardy shrubs have few blights or insect issues. Fireblight and leaf spot are possible.
