|This upright, deciduous shrub is an old-time favorite found in informal borders and hedges. Growing to a height of 10 feet tall and 6 feet wide, this shrub is loved primarily for its large, to 2 1/2 inches wide, funnel-shaped blooms that resemble those of the tropical hibiscus, yet not as flashy. Leaves are diamond-shaped, dark green, slightly palmate and toothed.
'Helene' bears white flowers with light burgundy bases from late summer until mid-fall. Soil should be well-drained neutral to slightly alkaline and sun should be full, though partial shade is tolerated. This plant really requires no pruning, unless you need to remove a dead or damaged branch. Native from China to India.
