Common Name:

General Information

Viburnum cylindricum is an evergreen shrub or small tree; it usually grows up to 8 metres tall, exceptionally reaching 15 metres. In cultivation it is likely to be no more than 5 metres tall[, ]
The plant is sometimes harvested from the wild for local use as a food, medicine and source of materials. It is cultivated for medicinal use in the homegardens of southern Yunnan[], can be used as a pioneer in reforestation and is sometimes grown as an ornamental..

Cultivation Details

Viburnum cylindricum has a range extending from the warm temperate regions of China and India (where it can be found at elevations up to 3,300 metres) to the tropical regions of Malaysia and Indonesia (usually at elevations in excess of 1,000 metres)[, ]. Selected provenances from the north of its range can tolerate considerable frost and are suitable for growing in the temperate zone, whilst provenances from the south are more suited to the tropics.
An easily grown plant, succeeding in most soils but ill-adapted for poor soils and dry situations[]. Prefers a deep rich loamy soil in sun or semi-shade[, ]. Best if given shade from the early morning sun in spring[].
Plants are self-incompatible and need to grow close to a genetically distinct plant in the same species in order to produce fruit and fertile seed[, ].
The flowers are sweetly scented[].

Edible Uses

An edible oil is obtained from the seed[, , , ]. It is used for cooking[].

Medicinal

The oil from the seed is used to soothe itchy skin[].

Agroforestry Uses:

This species is an early pioneer of deforested land[] and can be used as a pioneer in establishing a woodland garden[].

Other Uses

An oil from the seed is used as a luminant[].

The wood is hard, close grained[, ].

Propagation

Seed - best sown in a cold frame as soon as it is ripe. Germination can be slow, sometimes taking more than 18 months. If the seed is harvested 'green' (when it has fully developed but before it has fully ripened) and sown immediately in a cold frame, it should germinate in the spring[]. Stored seed will require 2 months warm then 3 months cold stratification and can still take 18 months to germinate[]. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in a cold frame or greenhouse. Plant out into their permanent positions in late spring or early summer of the following year.
Cuttings of soft-wood, early summer in a frame[]. Pot up into individual pots once they start to root and plant them out in late spring or early summer of the following year.
Cuttings of half-ripe wood, 5 - 8 cm long with a heel if possible, mid summer in a frame[, ]. Plant them into individual pots as soon as they start to root. These cuttings can be difficult to overwinter, it is best to keep them in a greenhouse or cold frame until the following spring before planting them out[].
Cuttings of mature wood, winter in a frame. They should root in early spring - pot them up when large enough to handle and plant them out in the summer if sufficient new growth is made, otherwise keep them in a cold frame for the next winter and then plant them out in the spring.
Layering of current seasons growth in mid summer. Takes 15 months[].
