Description

‘Diana’ rose of Sharon is a large deciduous shrub in the Malvaceae (mallow) family. It matures to a height of 5 to 8 feet and a width of 4 to 6 feet, so consider its space requirement when identifying its planting location. Its pure white flowers with no eye are tubular in shape and bloom in summer. Despite its name, rose of Sharon is not related to roses at all.

Plant in locations that receive full sun to partial shade and that have clay or loamy soil with good drainage and high in organic matter. It is a low-maintenance plant and has a medium growth rate. The plant is triploid, which means it does not produce seed. Rose of Sharon tolerates summer heat and humidity and wet sites and is resistant to black walnut rot. It is mildly resistant to deer damage.

Its flowers attract pollinators like hummingbirds, butterflies and bees so use it in a pollinator or naturalized garden. Plant multiples for use as a privacy screen or hedge.

Quick ID Hints:

  • large, tropical looking, 5-petaled flowers
  • erect, spreading habit with upright branches
  • 3-lobed leaves are 2-4 inches long
  • simple, alternate, coarsely toothed leaves
  • 5-valved, dehiscent capsule persists thru winter

Insects, Diseases, and Other Plant Problems: No serious problems
