Diabolo Ninebark is a deciduous shrub often chosen for its rich purple foliage.  The clusters of white flowers, which bloom in late spring, contrast nicely with the dark leaves.  Its attractive peeling bark gives this shrub additional winter interest.  Looks great with Annabelle Hydrangea!

  • Do I have to trim my Physocarpus in the fall ?

    • Hi Louise, The Physocarpus produce bloom buds in the fall so you always get a better bloom if you don’t prune it much. The can get large but they give quite the show if left un pruned if you have the space. I normally selectively remove branches to reduce the width after they bloom.
