Thamnocalamus spathiflorus, commonly known as Nepalese Bamboo, is an evergreen perennial grass native to the understory of high-altitude forests in the Eastern Himalayas. It typically grows to a height of 15-20 feet (5-6 meters) with a clumping habit and narrow width, often not exceeding a few inches across the clumps. This bamboo species is characterized by its powdery blue-green canes and delicate, feathery leaves that persist throughout the year, providing a unique texture in the garden.

Nepalese Bamboo is valued for its vertical accent and fine-textured foliage, which can add a soft, graceful appearance to landscapes. It is often used as a focal point in Asian-themed gardens, for screening purposes, or in containers. While it prefers full sun, it can tolerate part shade, especially in hotter climates. It requires medium amounts of water and can adapt to a range of soil drainage conditions, from slow to fast. However, it thrives best in moist, well-drained soils. Gardeners should be aware that, like many bamboos, Thamnocalamus spathiflorus can spread if not contained, and it may require regular maintenance to keep it within bounds. It is generally disease-resistant but can be susceptible to pests such as bamboo mites.CC BY-SA 4.0
