What it is

Bamboo refers to a large group of plants in the grass family. Even though most people think of bamboo as a kind of tree, it’s actually a type of grass — but one that can grow very tall and strong. There are about 1,200–1,250 species of bamboo in nature, and they vary a lot in size and shape.

There are generally two kinds of bamboo:

Most bamboos you see in gardens, forests, or along roadsides are the woody kind — tall, hollow-stemmed grasses that look like slim trees.


Where it grows

Bamboo originally comes from tropical and subtropical regions, especially Asia, where dense bamboo forests are common. You can also find bamboo in the Americas, Africa, Australia and even parts of Europe. Some hardy species can grow in cooler climates too — for example, in parts of Central Europe, the Caucasus, and Crimea.

In the Andes Mountains, certain species grow even at high elevations — up to about 4,700 m above sea level — forming nearly impassable thickets.


How it looks

Bamboo stems, called culms, are usually hollow and cylindrical, and can vary hugely in size:

Bamboo has long, narrow leaves and keeps its green foliage year-round, making it a common evergreen plant that stays attractive even in winter.


Flowers

One of the unusual things about bamboo is that it hardly ever flowers. Some species might only flower once every 20–100+ years, or even less often than that. When bamboo does bloom, it often happens over a large area at once — thousands of plants might flower, set seed, and then die. This strange lifecycle is still not fully understood by scientists.


How it is used

Bamboo isn’t just a plant that looks interesting — people use it in many practical ways:
