explanation !!!!
Ilex aquifolium, commonly called English holly, is native to Europe, western Asia and north Africa. It is an erect, pyramidal, densely-branched, evergreen tree that typically grows to 30-50' (less frequently to 80') tall. It also may be trained and grown as a large shrub (10-15' tall).
