A: Moso bamboo is a close relative of golden bamboo. Moso is the largest temperate bamboo, reaching heights of over 75 feet and with 5 inch diameter shoots. Two scientific names ‐ Phyllostachys pubescens and Phyllostachys edulis ‐ are currently used as scientific names for moso bamboo. Bamboo shoots emerge from horizontal underground stems called rhizomes. These rhizomes generally grow within the first 12 inches of soil. The real problem with this type of rhizome is it can spread or run outward 20 to 30 feet before sprouting. In addition, the rhizomes can run in all directions from the original shoot. This can become a weedy problem by growing in areas far from the original site – namely neighbor’s yards. We always recommend using clumping bamboo rather than running bamboo for that very reason.
