Introduction

Small and intermediate size trees play an important role in the landscape. They can be quite functional and offer seasonal beauty. These trees are generally very easy to maintain and require a minimum of pruning.

The limited space in urban settings requires the extensive use of small and intermediate sized trees. This is especially true in street, mall, and plaza projects, where a pavement will completely surround the tree and utilities (telephone, electrical) wires are either above or below ground. One needs to choose a tree which will remain relatively small in stature but offer large aesthetic benefits.

Residential landscapes utilize many of these trees as "understory" trees in natural areas where shade is a factor.

Blooms, berries and foliage color are also strong assets for most of the trees in this group.

Several of these trees are native to North Carolina, i.e., Flowering Dogwood, Redbud and River Birch. Care must be taken to assimilate these environmental conditions so the trees will grow and mature with a minimum of problems.
