Gymnocladus dioica KENTUCKY COFFEE TREE

This tree is adaptable to many soil conditions, including alkaline. The long "coffee beans" that gave it its common name are mahogany colored and decorative in the winter. The doubly-compound leaves give a lacy appearance in summer. The genus name means "naked branch", and after the leaves fall, the naked branches

give the tree a very picturesque winter appearance. 50' tall. Zone 4.

Juglans nigra BLACK WALNUT

This hardwood tree is fast growing. In optimum sites it can grow 3'-4' per year. It likes regular moisture during the growing season and needs full sun. 50' tall. Does not like late spring frosts, so plant in area where cold drains away. Hardy to zone 4.

Discovered approximately 40 years ago, this variety is much better than other poplars for our western growing conditions. Although it can survive drought, for faster growth it needs adequate water. 40' tall. Zone 3.

Populus tremuloides QUAKING ASPEN

A pioneer tree that regrows from its roots after a forest fire, aspen trees are found at high elevations in Colorado. The soft rustling of their leaves is one of nature's loveliest sounds. The leaves are attached by flattened petioles (leaf stems), joined at right angles to the leaf, so that they twist and flutter with the slightest breeze. 40'-70' tall at maturity. They live 150 years, although some colonies are much older. Zone 2.

Pseudotsuga menziesii 'Glauca' DOUGLAS FIR, ROCKY MOUNTAIN

This tree is common through the west; it flourishes in higher elevations but is probably not the tree for Pueblo. This is one of the fastest growing evergreens. Often used as a Christmas tree because of its great form, color, and because it holds its needles for such a long time. Zone 4.
