First scientifically described in 1985, Fargesia scabrida doesn’t seem to have a well-known common name. On the label for this plant growing at UBC Botanical Garden, we’ve opted to tentatively use “orange stem bamboo”.
It’s arguable whether that moniker will stand the test of time, as it isn’t actually the stems (or culms, in the case of bamboo) that are orange, but rather the culm sheaths. These thin pieces of tissue initially protect the developing culm. After it has elongated, the sheaths will remain on the culm for some period of time before falling to the ground. It is doubtful that the sheaths are protection against herbivory, as the sweet shoots are apparently a favoured food for the giant panda. To see photos of these orange culm sheaths, you can browse the images on this commercial site: Fargesia scabrida on plant lust.
Of course, being food for the giant panda means that this bamboo is native to China (and more specifically, southern Gansu and northern Sichuan). These plants were added to the David C. Lam Asian Garden in 2013 as part of an introduction of a number of clumping bamboo species.
Switching topics, and of particular interest to Canadian readers: you have one more week to vote for a proposed National Lichen for Canada (or read the press release from the Canadian Museum of Nature that also includes a link to vote). If interested, there is a discussion about the topic on the Garden’s forums: Canada’s National Lichen discussion. I personally didn’t vote for the Bryoria, but you may perhaps be swayed by the advocacy there!
