Hi. That is a type of bamboo. I’m not sure of the exact species offhand, but it is clearly a “running” bamboo. Such bamboos are notoriously difficult to control because they spread by strong, pointed, underground stems known as rhizomes. Your best strategy is to remove it by digging it out. This will be difficult work, but it is effective. If need be, you can use a non-selective herbicide such as glyphosate, but that can be problematic if it is mixed in with other plants you want to preserve. Clemson U. has a good page on controlling bamboo here. The University of California also has a good page here that includes additional links. If you do use an herbicide, be sure to read the instructions and follow label directions.
