This is one of many rather similar evergreen Meliosma species whose distribution extends south from China into the tropics of south-east Asia; it is included here on the basis of one collection from North Vietnam (TH 5092) which is grown at Tregrehan and Caerhays Castle, both in Cornwall, UK (Williams 2022). The flower-heads are smaller and duller than in the hardy, deciduous Meliosma species, and M. dumicola and its allies seem unlikely ever to be widely cultivated in the west.

At Tregrehan these plants have grown into densely-branched trees 6–7 m tall; they are yet to flower but have been confirmed as Meliosma dumicola by Frits van Beusokem (J. De Langhe pers. comm). The brilliant green, glossy leaves with long drip-tips are strikingly attractive, and have ‘always looked unbelievably fresh and chirpy even with freezing temperatures’ (T. Hudson pers. comm.). In spring, the new leaves are delicately red- or pink-flushed. The leaf-stalk is unusually long for the genus, giving the foliage an extra elegance.
