Physocarpus opulifolius 'Seward' , Summer Wine™ Ninebark
2007 Theodore Klein Plant Award Winner
Physocarpus opulifolius 'Seward' , Summer Wine™ Ninebark. This almost indestructible shrub is a standout for the summer garden. The mahogany foliage is deeper and holds its color better than other varieties and the overall growth is more uniform and compact than others as well. Grows to 4-6' tall and wide and is best in full sun. Tolerates most average garden soils. Propagated easily as summer softwood or fall cuttings without rooting hormone (Dirr says best in sand:peat medium). Seeds germinate immediately without stratification or scarification treatments.
