In autumn, the fruit will start to turn pink as the leaves start to take anywhere from dark green, burgundy, red, orange, yellow and purple. The fruit ripens to a blackish-blue end colour. Once all the leaves have fallen to the ground, its grey-brown bark and reddish-brown twigs are fully visible.

Propagation
Propagation by seed or cuttings. Once the seed is ripe, put into a cold frame at 5° C. From here it requires two months of warmth followed by another three months of cold. It can be planted thereafter but may still take up to eighteen months to germinate. Cuttings should ideally be 5 - 8 cm long, with a heel if possible. Cuttings need to be done between July and August, and then put into a cold frame until the following spring. By this point they should root and you can pot the plant until firmly rooted.
Ethnobotanical Uses (Disclaimer)
Bark and root bark used for traditional medicinal purposes.
