Some trees have two kinds of flowers on them – male flowers and female flowers. These catkins are male flowers. They are covered with pollen. The same tree also has small female flowers.
A holly tree can be male or female.
Holly trees or bushes are either all male or all female. Both male and female holly trees have white flowers. Berries only form on the female trees. To make new plants, there must be a male and female holly tree growing near each other. Insects carry pollen from the male to the female tree.
Both male and female flowers grow on a pine tree.
The male flowers are usually red or purple and the female flowers are often yellow or white. The female flower will become a pine cone if it is fertilized.
Most trees and bushes have flowers.
Some trees have flowers to attract insects, while others use the wind to spread pollen. Trees that use the wind usually have green, feathery flowers that hang from the tree.
