Female Holly Alaska A slow-growing evergreen tree, well known for its spiky leaves and red berries. Holly is tough, and robust enough to handle the harshest of environments from dark valleys to extreme coastal locations - though it thrives best with the protection of other trees around it. Berries come on female plants, so be sure to plant several cultivars to increase the chances of pollination. Ilex aquifolium Alaska is self fertile and will produce berries, it also makes a very attractive, slow-growing spiky hedge that clips very well and is an ideal evergreen to include in mixed hedges.
