Species growing 'wild' in Central CA
Sorry for the regional question. There is a species of bamboo that has presumably escaped cultivation and is growing on river/creek banks throughout the San Joaquin and Sacramento valleys. Sorry, no pic yet. It looks to get about 20 or so feet, culms an inch or a bit more in diameter. Green to tan culms without any discernible decoration, long green leaves.
Anybody know the species? I'm guessing a Phyllostachys sp., but that's only a guess.
