Himalayacalamus hookerianus, commonly known as Blue Bamboo or Himalayan Weeping Bamboo, is an evergreen perennial grass native to the understory of temperate forests in the Eastern Himalayas. It typically grows to a height of 20-30 feet (6-9 meters) with a narrow width, due to its clumping growth habit. This bamboo species features powdery blue-green canes and delicate, weeping foliage that adds a graceful appearance to the landscape.

Blue Bamboo is valued for its ornamental qualities, including its unique cane color and elegant form. It is often used in gardens for creating natural screens or as a focal point in Asian-themed gardens. While it thrives in full sun, it can also tolerate part shade, which makes it versatile for different garden settings. It prefers a well-drained soil and requires regular watering, especially during dry periods. Although it is a clumping bamboo and less invasive than running types, it can spread if not maintained. Gardeners should monitor its growth and may need to contain it with root barriers.CC BY-SA 4.0
