Plant Life: Look - but don't eat

It's mid-autumn and the fresh fruit covering Camellia yunnanensis look good enough to eat. They could easily be mistaken for apples, except they are a bit small. Their skin is mostly light green with a blush of sun-kissed red on top.

It's probably best not to sink your teeth into the fruit as it is not the sweet juicy fruit you would expect, but a hard, dry, thick-skinned capsule. The ornamental fruit capsule ripens on the small tree for several weeks before splitting and dropping to the ground, releasing several large brown seeds.

Camellia yunnanensis is a species occurring naturally in the wild.

It flowers in spring. The flowers are solitary and pure white, with a cluster of bright yellow stamens. The flower buds are fat and round, up to 2cm across just before they open. They then open into a single broad cup-shaped arrangement of seven to twelve petals. The bark of this camellia is a cinnamon colour with a velvety smooth surface.

C. yunnanensis grows in southwest China, in the province of its namesake - Yunnan - as well as Guizhou and Sichuan provinces.

It grows wild in mountainous forest and thickets at an altitude between 1100m-3200m above sea level. As a comparison, New Zealand's Mt Cook is 3754m above sea level.

This slow-growing camellia grows to 1m-5m tall.

There are specimens of C. yunnanensis in fruit in the lower botanic garden camellia collection.
