Ligustrum quihoui


Waxyleaf privet

Synonym(s):
Family: Oleaceae (Olive Family)
Duration and Habit: Perennial Shrub

Description

Ligustrum quihoui is a semi-evergreen to evergreen shrub, one to three meters high. It can be easily confused with the morphologically similar Ligustrum sinense (Chinese privet), but can be distinguished by its narrower leaves, highly divaricate branching habit, and narrower inflorescence.

Native Lookalikes: Currently no information available here yet, or there are no native Texas species that could be confused with Waxyleaf privet.

Ecological Threat: It is not nearly as invasive as Ligustrum sinense but this privet species can also out-compete native vegetation and when not controlled can create a monoculture and change the understory of a forest.

Biology & Spread: Birds disperse seeds readily.

History: Introduced as an ornamental

U.S. Habitat: Forested areas.

Distribution

U.S. Nativity: Introduced to U.S.

Native Origin: China

U.S. Present: AR, FL, NC, TX, VA

Distribution in Texas: Reports from central, east and north Texas.

Native Alternatives

Other alternatives include inkberry (Ilex glabra), spicebush (Lindera benzoin), blackhaw (Viburnum prunifolium), red or black chokeberry (Aronia arbutifolia or melanocarpa)

Management

Chemical: Foliar application with one of the following herbicides in water with a surfactant (August to December):
Glyphosate herbicide as a 3-percent solution (12 ounces per 3-gallon mix)
Arsenal AC* as a 1-percent solution (4 ounces per 3-gallon mix).
For stems too tall for foliar sprays, apply Garlon 4 as a 20-percent solution in commercially available basal oil, diesel fuel, or kerosene (2.5 quarts per 3-gallon mix) with a penetrant (check with herbicide distributor) to young bark as a basal spray.
Cut Stump approach: Cut large stems and immediately treat the stumps with Arsenal AC* or Velpar L* as a 10-percent solution in water (1 quart per 3-gallon mix) with a surfactant. When safety to surrounding vegetation is desired, immediately treat stumps and cut stems with Garlon 3A or a glyphosate herbicide as a 20-percent solution in water (2.5 quarts per 3-gallon mix) with a surfactant.

USE PESTICIDES WISELY: ALWAYS READ THE ENTIRE PESTICIDE LABEL CAREFULLY, FOLLOW ALL MIXING AND APPLICATION INSTRUCTIONS AND WEAR ALL RECOMMENDED PERSONAL PROTECTIVE GEAR AND CLOTHING.
