Japanese Bamboo Plant
If you’re searching for Japanese bamboo plant than you’re probably either looking for Phyllostachys bambusoides or Polygonum cuspidatum. Phyllostachys bambusoides or Japanese timber bamboo is a running bamboo species. This beautiful bamboo plant is capable of reaching up to 60 feet high and 5 inches in diameter. It’s not known to do well in cold weather and is thus recommended for zones 7-10.
An Imposter (But Still Cool Plant)
Polygonum cuspidatum on the other hand is a plant that resembles bamboo-but isn’t. Its common name is the Japanese Knotweed. Japanese Knotweed grows best in the northeastern states and is often considered (as the name suggests) to be a weed. Japanese Knotweed grows up to 8 feet tall and spreads quickly and aggressively due to rhizomes and running roots which can take the sucker up to 30 feet away from the parent plant. Because of this, it’s a good idea to plant Japanese bamboo in pots instead of directly in the ground. Another great reason to plant Japanese bamboo in a container, is that it is sensitive to adverse weather and strong wind and being in a pot will allow it to be moved seasonally. Also like bamboo, Japanese Knotweed plants prefer well-drained soil and at least 6 hours of sun a day.
