Description

Chimonobambusa quadrangularis, commonly known as Square Bamboo or Green Square Bamboo, is a species of bamboo native to parts of East Asia, particularly China and Japan. It belongs to the grass family Poaceae and, as the name suggests, its culms are distinctly square, which sets it apart from other bamboo species. This distinct feature adds to its visual appeal, making it a popular choice for ornamental purposes.

Typically reaching a height of about 6 to 9 feet (1.8 to 2.7 meters), it is a relatively compact bamboo variety. This makes it suitable for Planters and pots for smaller garden patios.

The leaves of Chimonobambusa quadrangularis are medium to dark green in colour and have a lanceolate shape. They are arranged alternately along the culms and create an attractive clumping effect.

The culms of Chimonobambusa quadrangularis have a vibrant green colour, especially in their early growth stages. As they mature, the culms develop a brownish-green hue, giving the bamboo a unique visual appeal. The culm surface is smooth and has a glossy texture.

Chimonobambusa quadrangularis is a running bamboo species, known to spread and develop extensive underground rhizome systems, allowing it to propagate rapidly and potentially be invasive. Unlike clumping bamboos, running bamboos can spread over a larger area if not properly managed. Therefore, it is important to consider containment methods when planting running bamboo species like Chimonobambusa quadrangularis.

This bamboo species has a relatively high cold tolerance, with some sources indicating it can withstand temperatures as low as -26°C.

Under optimal conditions, Phyllostachys bambusoides can reach its maximum height within 5 to 10 years. It is known to grow at a rate of around 2 to 5 feet per year.

Square Bamboo is primarily used for ornamental purposes due to its unique square culms and attractive appearance. It can be grown in Planters and Pots. Some people also use the culms for crafts or decorative purposes.
