EUROPEAN PRIVET [Ligustrum vulare L.] LIVU Fig. 1 UGA 5369085 Problem: Native to Europe, L. vulgare. was brought to North America as an ornamental in the 1700’s.1 It escaped cultivation and displaces native species by forming dense thickets.2 Habit: Stout, multi-stem trunk growing up to 4.5 m tall with unevenly spreading branches.3 Often as wide as tall.4 Stems and leaves at near right angles.5 Reproduction: Sexually by seeds from drupes which are widely disseminated by birds.4 Leaves: Simple, opposite, ovate to elliptic, margins entire. Lustrous green above and pale green beneath, turning purple in the fall. 2.5-7 cm long.2, 4 Fig. 2 UGA 5272067 SHRUBPLANT EUROPEAN PRIVET Ligustrum vulgare L. Fig. 3 UGA 5397688 Fruits/Seeds: Lustrous4 dark purple to black, spherical, about 8.5mm long drupe.3 Flowers: Arranged in a terminal 2.5-7.5 cm panicle.2 Individual flowers small (2.5-3 mm)6 are tubular with four lobes that are equal or less than the length of the tube. Sta- mens are mostly included or slightly projecting from tube.6 Flowers are white, with a strong scent.2 Habitat: Full sun or partial shade.4 Often found in areas of disturbed soil, along streams, and in the forest understory (though it does not produce seed in low light).1, 3 Similar Species: Ligustrum species are difficult to distin- guish vegetatively. L. obtusifolium has a flower tube about twice as long its the lobesGC and its leaves are smaller, blunt-tipped, and have a pubescent mid-rib.7 Fig. 4 UGA 5272068 Ligustrum vulgare (European privet) Text Citations: 1.
