Thamnocalamus tessellatus


Max/Avg Height (ft.): 20, 12-15

Diameter: 1 inch

Hardiness: 10º F

USDA Zones: 8-9, Not recommended for climates with a lot of intense heat or high summer humidity (including most of the southern USA)

One of the best clumping bamboos for a sunny location. It is also more upright than our other hardy clumping bamboos. This bamboo is from South Africa, where it is called Bergbamboes, or mountain bamboo; it is the only African bamboo hardy enough to grow in the Pacific Northwest. It is an unusual bamboo, having very thick culms in relation to its height. As you can see from the pictures, it forms a tight clump, unlike the open clump reported in some publications. It is also quite wind tolerant and can be used in coastal landscapes.

Although it can grow in zone 7 through 9, it will usually show some foliar damage when exposed to temperatures of 12 F or lower.  At 0F, it will likely loose many canes, in addition to the leaves.
