Native range
Southern China, Korea, Japan, Taiwan and into India and south-east Asia — dry hillsides, scrub and rocky ground. Widely known in the West only as a bonsai subject.
Status
Both wild and cultivated
Years to fruit
3–4 yrs to flower, then 3–6 more to ripen
Growth speed
Moderate to fast, and it responds to hard cutting — the reason it is a bonsai standard
Spacing
150 cm (59 in) apart — about 2.3 m² (24 sq ft) per plant
Leaf shape
Small, evergreen to semi-evergreen, ovate 1–4 cm, glossy and finely toothed, in near-opposite pairs on spiny, zig-zagging twigs. New growth flushes bronze-pink.
Root system
Shallow, dense and fibrous, tolerant of drought and of the severe root pruning bonsai culture involves — an unusually forgiving root system.
Fruit description
Small purple-black drupes 4–5 mm ripening in autumn, sweet and pleasant but slight — a nibbling fruit. The young leaves are dried and brewed as a tea in southern China, which is where the name 'sweet tea' comes from.
Propagation
Semi-hardwood cuttings root easily; layering works; seed is straightforward after cleaning. Nothing about this plant is difficult to propagate.
Pollination
Self-fertile — flowers are hermaphrodite

About the data

Zone figures are typical published ranges — microclimate, drainage and siting shift them by a zone in either direction. Store links are found by an automated search, refreshed every six weeks. Availability is seasonal; stock and prices are not tracked.
