Q.difference between American holly and English holly
What is the difference between an American holly and an English holly? I am being told that the berries on the American holly are above the leaves and that on the English holly they are below the leaves. Is this correct?

The differences can be subtle.
English Holly leaves are a deep green and glossy.
American Holly is a more yellow green color and are a dull finish.
If the leaves are variegated they are English.
English Holly leaves curl under a bit and American Hollies are flat with spines that stick straight out.
English Holly can grow 15 to 20 feet tall with a very dense growing form. American Holly can grow up to 60 feet and will have a more openly spaced canopy.
The berries are not really an indicator.
