Problems with this Plant.

Webworms will attack this plant.  Also commonly called “fall webworms”.  They feed on the foliage of many types of trees and shrubs.  They make large silk webs on the ends of stems or branches.  Spraying with a product called “Thuricide will kill them”. Thuricide is a liquid form of bacteria, Bacillus Thuringiensis or more commonly known as “BT”.

Go organic and pick them out by using tweezers or place a water bowl nearby for birds.  Most birds will eat caterpillars and webworms.

Growth Rate

Moderate growing plant.  Will reach 6 ft. in about 4-5 years.  Prune in late winter to enhance new growth and flowers in early to mid-spring.  You can read more details about this plant over at
