Phyllostachys vivax

Common name: Giant timber bamboo · Chinese timber bamboo · Vivax bamboo

Phyllostachys vivax is a giant running timber bamboo native to eastern China, prized for its tall, thick-walled green culms and dense canopy of glossy leaves. It is among the fastest-growing bamboos in cultivation, sending up new shoots in spring that reach their full height in a single season. Gardeners grow it for dramatic screens, windbreaks, and timber production, though its running rhizomes demand containment in most settings.

Fun facts

  • New spring shoots can grow over a meter per week, making it one of the fastest-growing temperate bamboos.
  • Mature culms can reach 5 inches (13 cm) in diameter and are used for construction and furniture.
  • The cultivar 'Aureocaulis' has striking golden-yellow canes randomly striped with green.
  • Though a vigorous runner in warm climates, its spread slows noticeably where winters are cold.
