Privet

A genus of approximately 50 species of deciduous and evergreen trees and shrubs native to Europe, Asia and northern Africa. They are distant relatives of the Ashes, Lilac and Olive.
Most thrive in sun or shade on most types of soil and are tolerant of pollution and salt. Alkaline soil tolerant.
In dry climates, mulch to preserve moisture.
The roots are greedy. Privet regenerate freely when cut back hard in spring just before the new growth begins. Hedging plants should be cut back hard to a foot tall upon planting and pruned hard for the following 2 years to encourage dense habit.
On the contrary, larger species can be trained to single trunk, feathered with lower branches gradually limbed up to encourage an attractive tree. Shrub forms can also be left to their own devise to develop their naturally attractive form.
The species are grown from seed sown when ripened. The cultivars are sown from firm tip cuttings taken during late spring and summer.
The Privets are not generally eaten by deer.
