Myoporum laetum is an evergreen shrub or small tree belonging to the family Myoporaceae, and is native to New Zealand. This evergreen species may reach a height of up to 10 m. It produces small white flowers from late winter to mid-spring. It is a fast-growing plant, initially forming a dense and attractive canopy; however, with age, older branches tend to deteriorate and are eventually shed.

The leaves contain numerous small oil glands, visible as tiny yellowish-white dots on the leaf surface. This distinctive leaf appearance clearly differentiates Myoporum laetum from other shrubs. The flowers are white and marked with purple spots, while the fruits are purplish-red drupes.

The species is commonly used as an ornamental plant, particularly for roadside plantings and as a hedging species. Although not widely known in our country, Myoporum laetum has shown invasive tendencies in parts of America and Europe, where it has spread beyond cultivated areas and established populations in natural habitats.

It has been reported that Myoporum can invade native vegetation. When it becomes dominant, its dense shade suppresses the growth of other plant species beneath it. The leaves contain toxic chemical compounds capable of causing liver damage in sheep and cattle; therefore, the cultivation of this species should be avoided near grazing areas. Myoporum laetum produces abundant seeds, which are dispersed over long distances by birds that feed on the fruits.

Propagation of Myoporum laetum is carried out by seed or cuttings. When propagated from seed, it is recommended that the seeds be subjected to cold stratification for approximately eight weeks prior to sowing.
