They are the fastest-growing plants, but How Fast Do Giant Bamboos Grow in the UK?
Kew Royal Botanic Gardens has one of the largest collections of garden bamboos in the UK. At Kew’s Tropical Glass House you’ll see the giant bamboos.
- Gigantochloa verticillate Giant Bamboo.
- Bambusa Ventricosa Buddha’s Belly Bamboo.
- Bambusa vulgaris – the Common Bamboo.
The three Giant Bamboos are a must-see. Kew Bamboo Garden also has 130 different bamboos growing naturally.
How fast does Giant Bamboo (Gigantochloa verticillate) Grow in the UK? 
The giant bamboo Gigantochloa verticillate at Kew Garden grows to 2.4 metres in just 16 days. To put it in perspective, the giant bamboo grows at a rate of 15 cm per day.
Think about 30 cm, that is a typical classroom ruler is 30 cm, right? That would be how tall the bamboo grow in just 2 days.
There are several factors that affect the growth of the bamboo plants such as humidity, sunlight, soil and moisture. In Kew’s Tropical Glass House, the conditions are right for the bamboo plants. The greenhouse imitates tropical conditions, that is why the bamboo grows at this absolutely crazy rate.
As for UK bamboos, we measure the growth rate of Phyllostachys aureosulcata spectabilis in Summer (one of the common garden bamboos in the UK). This running bamboo grows at a rate of 1.43 cm per day. Take a look at how we measured and calculated how fast bamboo grows in a day.
Gigantochloa verticillate Giant Bamboo
Here is what Kew said about the giant bamboo:
The giant bamboo is the largest of all the bamboos. It grows 25-30 metres in the wild, as tall as a tree. This bamboo is native to Southeast Asia and the Pacific, particularly China and Papua New Guinea.
In the greenhouse at Kew Gardens, this bamboo reached the top of the ceiling and had to be cut.
Uses of Giant Bamboo plants
The giant bamboos are so versatile, they earn the name ‘friends of the people’. They are used in buildings, paper making, utensils and tools, musical instruments and even for food. They also protect watershed areas from flooding. In mountainsides, they are important barriers for preventing soil erosion.
However, the giant bamboo natural habitats have now been lost to urbanisation and agricultural land use. Yet, it is often planted in stands as a source of building materials.
Bambusa Ventricosa Buddha’s Belly Bamboo
Another large bamboo in Kew’s Tropical Glass House is the popular Buddha’s Belly Bamboo. Its peculiar shiny green culms are a standout – you will hardly miss it.
The swollen or bulging internodes of its culms resemble Buddha’s fat belly that is why it earns the name Buddha’s Belly Bamboo. The culms are deep dark green smooth and glossy with multiple branches growing at each node.
Bambusa Ventricosa (Buddha’s Belly Bamboo) is probably the most peculiar-shaped bamboo that also grows in the UK. It has a clumping nature, great as a pot plant or garden plant.
Bambusa vulgaris – the Common Bamboo
This giant tropical bamboo also grows in Kew Tropical Glass House, also known as the Common Bamboo. An amazing bamboo with glossy green culms, large brown sheaths and hairy rims around the nodes.
This giant timber bamboo is predominantly used for buildings and constructions and stakes for large garden plants like bananas and sugar canes.
