Abstract
The tree of this invention is the `Wilton Pyramidal Yew` which was derived from the chance pollination between the Taxus cuspidata and the Taxus media `Hatfield`. It is a male plant and produces no seeds. It can be reproduced asexually only from terminal cuttings. The `Wilton Pyramidal Yew` is a broad base tree with a limited number of terminal cuttings located only at the top of the tree. It has a relatively slow rate of growth, is of a rich green color, and the leaves extend well into the interior of the tree from the top to the base making it adaptable for deep pruning without uncovering bare branches.
