Several species of this genus are commonly cultivated, especially for hedges, and they doubtless escape far more often than the maps suggest. Numerous cultivars have been named, as have hybrids of L. vulgare × L. ovalifolium (L. ×vicaryi Rehder) and L. obtusifolium and L. ovalifolium (Ligustrum ×ibolium Coe).

1. Corolla tube equaling or shorter than the lobes; leaves glabrous; twigs and pedicels glabrate to finely puberulent (hairs all or mostly less than 0.2 mm long).

L. vulgare

1. Corolla tube about twice as long as lobes, or longer; leaves glabrous or pubescent; twigs and pedicels glabrous or pubescent with many hairs over 0.2 mm long.

2. Twigs, pedicels, calyx, and midrib of leaves beneath pubescent with many of the hairs over 0.2 mm long; leaves promptly deciduous.

L. obtusifolium

2. Twigs, pedicels, calyx, and leaves glabrous or nearly so; leaves persistent well into winter.
