Hydrangea arborescens ‘Riven Lace’

4 Photos


The lacecap cultivars Hydrangea arborescens ‘Riven Lace’, Hydrangea arborescens ‘Emerald Lace’ and Hydrangea arborescens ‘Green Dragon’ are compact plants with deeply serrated, almost twisted foliage that is quite different from other hydrangeas. It is widely accepted that these three cultivars were originally selected from a wild hydrangea population in Illinois and are in fact the same plant. During the trial, these cultivars had essentially identical results and thus are grouped together.  They did not tolerate full sun exposure, and even in shade exhibited leaf burn and premature defoliation.  Additionally, these cultivars attracted very low numbers of pollinators. The paucity of pollinator visits could be attributed to several factors including the possibility that these cultivars do not offer the same quantity or quality of nectar and pollen rewards as other lacecaps in the trial.
