Roses
There were roses millions of years ago. They grow all round the world. In 1597 there was a book with a list of only nine different roses, but now there are more than 3,000 different roses.
Roses grow on bushes, trees and climbing plants.
They are many different colours and shapes, and they do not all have the same number of petals. They all have different names, too!
Roses are beautiful and some of them smell very nice, too. There are many stories and poems about roses, and many people like to give roses for presents.
The largest rose tree in the world is in the United States. Its trunk is 101 centimetres thick and it is 2.74 metres tall. 150 people can sit under the tree at the same time!
