Growth—

Ligustrum japonicum is native to the warm temperate zone of southeast China, Japan and Korea. A somewhat cold-tolerant plant, when fully dormant it can withstand short periods with temperatures down to about -15°c, though new growth can be damaged by frosts in the spring. It succeeds in regions with a mean annual rainfall within the range 975 - 2,400 metres[2]. Succeeds in sun or semi-shade[3]. A very tolerant and easily grown plant, it succeeds in any soil that is not impoverished or water-logged[4, 5]. Grows well in heavy clay soils. Prefers a pH in the range 6.1 - 7.8[2]. Tolerant of atmospheric pollution, the plant can grow well in cities[2]. Plants respond well to trimming and even old wood can resprout from the ground if the plant is cut back severely[2]. Fast-growing when young, but it soon slows down with age[2]. This species is closely related to Ligustrum lucidum[4, 6]. There are many named varieties selected for their ornamental value[6]. The panicles of creamy white flowers are fragrant[2]. This species is notably resistant to honey fungus[6].

Propagation

The seed does not require any pre-treatment and can be sown in the spring in a cold frame[7]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, 5 - 10cm with a heel, mid summer in a frame. Very easy[8]. Cuttings of mature wood, 20 - 30cm in a sheltered outdoor bed in late autumn. High percentage[8].
