A tall, spreading shade tree with interestingly shaped leaves that turn brilliant yellow, orange, red and purple in fall; somewhat particular about growing conditions; fruit is spiny and can be somewhat messy, use where this will not be a problem
Sweet Gum has forest green foliage throughout the season. The lobed palmate leaves turn an outstanding crimson in the fall. Neither the flowers nor the fruit are ornamentally significant. However, the fruit can be messy in the landscape and may require occasional clean-up.
Sweet Gum is a deciduous tree with a strong central leader and a shapely oval form. Its average texture blends into the landscape, but can be balanced by one or two finer or coarser trees or shrubs for an effective composition.
This is a high maintenance tree that will require regular care and upkeep, and is best pruned in late winter once the threat of extreme cold has passed. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats.

Planting & Growing
Sweet Gum will grow to be about 70 feet tall at maturity, with a spread of 50 feet. It has a high canopy of foliage that sits well above the ground, and should not be planted underneath power lines. As it matures, the lower branches of this tree can be strategically removed to create a high enough canopy to support unobstructed human traffic underneath. It grows at a fast rate, and under ideal conditions can be expected to live for 80 years or more.
This tree should only be grown in full sunlight. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is very fussy about its soil conditions and must have rich, acidic soils to ensure success, and is subject to chlorosis (yellowing) of the leaves in alkaline soils. It is somewhat tolerant of urban pollution. This species is native to parts of North America.
