Family: Poaceae

Origin, Description & Uses
Phyllostachys edulis, commonly known as moso bamboo or tortoise-shell bamboo, is a giant running bamboo native to central and southern China and Taiwan. It is one of the largest temperate bamboo species in the world, capable of growing into dense stands with tall, woody culms reaching over 50 feet in height. The species is widely cultivated for timber, edible bamboo shoots, erosion control, ornamental landscaping, and traditional construction materials. Moso bamboo is valued for its rapid growth, elegant appearance, and versatility, and is extensively grown in Asia for flooring, furniture, paper products, and garden plantings.

Risks & Threats
Although Phyllostachys edulis is not currently known to be naturalized in the Hawaiian Islands, it possesses several traits that are cause for concern in tropical island ecosystems. This species spreads aggressively through extensive underground rhizomes that can rapidly form dense thickets, crowding out native vegetation and altering habitat structure. Large bamboo stands may reduce biodiversity, change soil conditions, interfere with stream corridors, and create management challenges due to the plant’s persistence and difficulty of removal once established. Its vigorous growth and ability to expand beyond cultivation increase the risk of escape into natural areas. Because of these concerns, Plant Pono recommends choosing a low risk or native alternative whenever suitable alternatives are available.

High Risk Traits:

• Elevation range exceeds 1000 m, demonstrating environmental versatility
  
• Thrives in subtropical climates
  
• Naturalized (persisting and spreading after cultivation) in Japan, Taiwan and potentially elsewhere
  
• A potential landscaping weed
  
• An environmental weed in Japan and China (impacts diversity and ecosystem processes)
  
• Other Phyllostachys species are invasive
  
• Allelopathic
  
• Host of bamboo borer
  
• Forms dense monocultures, excluding other vegetation
  
• Reproduces by seeds (rarely) and vegetatively by rhizomes
  
• Self-compatible (but rarely flowers)
  
• May be dispersed by rhizome fragments, and intentionally by people
  
• Able to resprout after repeated cutting and pruning

Low Risk Traits:

• Unarmed (no spines, thorns, or burrs)
  
• Provides fodder for livestock
  
• Valued for food, as an ornamental and for construction material
  
• Reaches maturity after several decades of growth (67 years documented)
  
• Lack of flowering for much of life cycle limits potential for long distance dispersal
  
• Herbicides provide effective control on congeneric taxa
