A hardy bamboo that has a yellow strip on a dark green culm. This is one of the hardiest bamboos. Although one out of about 10 culms have abrupt zig-zags in the lower portion, it is rigidly upright, which makes it good to plant near a walk or driveway to create an evergreen screen for privacy. Phyllostachys aureosulcata usually begins shooting for us here in Portland during the second week in February. A fast and reliable grower in almost any climate.
