A stunning exclamation point for the garden; star-like foliage turns orange, red and burgundy in the fall; spiky one inch rounded fruit tends to fall into the mulch

Planting & Growing
Slender Silhouette Sweet Gum will grow to be about 50 feet tall at maturity, with a spread of 6 feet. It has a high canopy with a typical clearance of 5 feet from the ground, and should not be planted underneath power lines. It grows at a fast rate, and under ideal conditions can be expected to live for 70 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, and will benefit from being planted in a relatively sheltered location. This is a selection of a native North American species.
