Thyrsostachys siamensis, commonly known as Siamese Bamboo, is a striking bamboo species native to Southeast Asia, particularly found in Thailand, Laos, and Cambodia. This bamboo is celebrated for its distinctive appearance, with a combination of tall, slender culms and beautiful foliage that makes it an attractive addition to gardens, landscapes, and even functional applications. Thyrsostachys siamensis typically grows to a height of 8 to 14 meters, with culms ranging from 2 to 7,5 cm in diameter, which gives it a moderate size suitable for a variety of landscape designs.
The culms of Thyrsostachys siamensis are upright, smooth, and slender, with a striking green color that may gradually turn yellow or light brown as they mature. The bamboo’s tall, graceful stems grow in dense, vertical clumps, creating a formal, elegant appearance. The internodes are relatively long, contributing to the bamboo's overall light and airy look. Its upright growth habit makes it ideal for creating vertical accents or screens in gardens where space is at a premium.
