Holly is a slow growing tree and on female plants it bears red berries. Holly berries are used for decoration in houses at Christmas time.
Only female plants of holly have berries, and even then, a male plant must be close by to provide pollen. To know if a plant without berries is a male or female tree, you need to have a look at the flowers. The flowers are small and white, they are produced in April or May and are amongst the leaves.
In many parts of Ireland it is considered unlucky to cut down a holly tree, instead they are often left to grow as larger plants in the hedgerows.
Holly is an attractive tree in the garden and can be used as a hedge.
