Crinkle Leaf

Ligustrum japonicum (li-GUS-trum juh-PON-ih-kum re-cur-vi-FOH-lee-um)

Family: Oleaceae Non-native Understory

This plant is problematic, and alternatives should be considered. Please see the suggestions in the left-hand column. Crinkle-leaf privet is an erect, evergreen shrub or small accent tree with curved leaves. It is a member of the olive family (Oleaceae). The cultivar epithet is Latin and means that the leaves are curved backward (or downward). It is alkaline-, pollution-, sun- and shade-tolerant, as well as cold-hardy. It tolerates dry conditions and is intolerant of wet soils. It is susceptible to copper deficiency and various insect pests (see below). This plant flowers in late spring and produces an odor that is offensive to many people. It has lustrous dark-green evergreen foliage that makes this plant useful in foundation planting, as a privacy screen, as a hedge, or even for planting in a container. This plant has a somewhat more open growth habit than the wild-type species and is hardier than other cultivars. It can be pruned; however, keep in mind that next year's blossoms will appear on new growth. This cultivar is not presently known to be invasive, but the possibility exists that this might revert to the wild-type species and become a pest. This cultivar is not recommended for gardens in the Southeast. Quick ID Hints: lustrous dark green, simple, entire leaves with indistinct veins leaves have undulating margins and are twisted at the tip prominent lenticels on the bark Insects, Diseases, and Other Plant Problems: Whiteflies, Japanese and ligustrum weevils, white peach scale, and privet rust mites are common insect problems. Anthracnose, twig blight, cankers, powdery mildew, and root rot are common disease problems. Susceptible to copper deficiency. It can be weedy in disturbed areas and has escaped and naturalized in moist areas. The berries produced by this plant are toxic. Dogs can be adversely affected by eating the berries or leaves of privet. More information on Ligustrum japonicum .
