Description and Growing Information

ShapeBroad spreading shrub.
LandscapeUsed as a mass or single specimen in full sun to partial shade. Since it is a large, broad spreading plant it should be given room to grow.
PropagationSummer cuttings from June to September. According to Michael Dirr the plant is easy to root if his guidelines are followed.
CultivationEasy to grow but in our climate needs to be sited in partial shade and out of harmful winter winds. Heavy mulch is recommended and supplemental watering is necessary in our often dry summers.
PestsFew that are serious although I have experienced wilt or vascular collapse on some stems of some plants. They seem to overcome this if they are in good vigour.
Notable Specimens Royal Botanical Gardens, Burlington, Ontario, Canada.
HabitatHorticultural origin.
