Coppertina Ninebark (Physocarpus opulifolious) is a new hybrid between Dart's Gold and Diabolo that flushes an attractive copper in spring and transforms to a rich red in summer. Soft pink flowers line the gently arching branches in early summer. Tiny blossoms appear on top of reddish-brown leaves in April in warmer climates. In the cool/cold areas of its range, you’ll see flowers in mid-summer.
The foliage reddens as the season's progress. The flower buds are set during the summer, so don't cut it back late in the season. Coppertina Ninebark enjoys a wide range of hardiness, from USDA Zones 3 to 8.
This is the second shrub from Proven Winners to win this award in 5 years. ‘Limelight’ Hydrangea was recognized by the ASCFG as “2007 Fresh Cut Flower of the Year,”
