Phyllostachys
Phyllostachys, commonly known as running bamboo, is a genus of the grass family that comprises approximately 50 species. Native to East Asia, this genus is one of the most widely grown and well-known bamboo.
Habit: Phyllostachys bamboos are characterized by their upright, arching growth habit. These bamboos exhibit “running” rhizomes, meaning they spread rapidly and widely, quickly forming large colonies if not contained. Their hollow, cylindrical canes, or culms, range in height from 10 to over 100 feet (3-30 meters), depending on the species. The color of the culms varies, including shades of green, golden, and black.
Leaves: The leaves of Phyllostachys are lanceolate, meaning they are shaped like a lance head, with a pointed tip and broader base. They are generally green, although the color can vary from bright, fresh green to a darker, glossier hue. The leaves are deciduous and will drop and regrow seasonally.
Hardiness: The hardiness of Phyllostachys varies greatly by species. Most are quite frost-hardy, surviving winters in USDA zones 7-11. Some species are more cold-hardy and can survive in zone 5.
Flowers: Flowering in Phyllostachys is a rare and unpredictable event, often occurring in intervals of many decades. When a plant does flower, it often indicates the end of its life cycle. The flowers are small and inconspicuous.
Uses and Benefits: Phyllostachys bamboos have numerous applications. They are widely used in landscaping for screens, hedges, or as specimen plants due to their attractive appearance and rapid growth. Beyond this, Phyllostachys is also valued for its timber, which can be used in construction, furniture making, and crafting musical instruments. Certain species, such as Phyllostachys edulis, produce edible shoots that are a popular ingredient in many Asian cuisines.
Bamboos, including Phyllostachys, are also excellent for soil stabilization and can play a role in carbon sequestration due to their rapid growth rate. However, their invasive nature requires responsible planting and management to prevent unwanted spread.
