Normally we refer to small trees as those less than 25 to 30 feet in height.
Small trees are ideal for informal groupings as they require much less room than larger specimens.
Many small trees provide major interest and accent with seasonal bloom, seed pods, and fall color, thus making excellent specimen plantings. They are best used as secondary plantings with larger trees on the homegrounds. There is no perfect tree. All have good and bad qualities. Problems Mimosa Albizzia julibrissin 35 ft. x 35 ft.
