L. ovalifolium is a vigorous, upright, evergreen or semi-evergreen shrub with

               oval, rich green leaves to 6cm long. White flowers are borne in dense panicles to
               10cm in midSummer followed by spherical, shiny, black fruit. Originally native
               to Japan, the Oval Leaf Privet can reach heights of 4metres with a 4metre spread.
                    Ligustrum vulgare/Common Privet
                    L. vulgare is a deciduous or semi-evergreen shrub with narrowly oval, dark-
               green leaves to 6cm long. White flowers are produced in panicles to 5cm long in
               early  and  midSummer  followed  by  spherical  black  fruit.  In  its  native  Europe,
               north Africa and Asia, the Common Privet is less vigorous than the Oval Leaf
               Privet but can still reach heights of 3metres with a 3metre spread.
                    Ligustrum sinense
                    L. sinense is a vigorous, bushy, tree-like, deciduous or semi-evergreen shrub
               with  arching  branches  and  elliptic-oblong  pale  green  leaves  to  7cm.  White
               flowers  are  profusely  borne  in  panicles  to  10cm  long  in  midSummer  and  are
               followed by black spherical fruit. In its native China, Ligustrum sinense reaches
               heights of 4metres with a 4metre spread.
                    Bonsai Cultivation Notes

                    Position Full sun or shade, Privets are very tolerant of both full sun in the
               Summer and quite deep shade. Privet are fully hardy and only require additional
               frost protection when temperatures drop below -10°C, however during the winter
               the colder the temperatures Privet are exposed to, the more leaves they drop; this
               is a natural reaction and causes no permanent damage even when specimens lose
               all their leaves in severe cold. The following Spring, new growth very quickly
               replaces any foliage lost during the Winter. Ligustrum are also sold as indoor
               bonsai  and  will  also  tolerate  indoor  growing  conditions  as  long  as  humidity
               levels remain reasonably high with the use of humidity trays. Ligustrum that are
               left outside during the Winter must have spent the Autumn outside in order to
               acclimatise to the cold. Do not place trees that have been grown inside straight
               outside in the Winter as they will not have hardened off and it is better to leave
               them inside until Spring.

                    Feeding Feed fortnightly during the growing season, indoor species should
               only be fed monthly during the Winter whilst in active growth.
                    Repotting Annually in Spring as new buds extend; use a basic soil mix.
                    Pruning Trim to shape through the growing season, remove over large leaves
               and shoots with over long internodes. Hard prune during the late Winter or early
               Spring  before  new  growth  starts.  Wiring  can  be  carried  out  anytime,  though
               Spring-Summer is best.
                    Propagation Sow seed outside in Autumn or Spring. Take semi-ripe cuttings
               in Summer or hardwood cuttings in Winter. Airlayerings can be taken in late-
