Liquidambar orientalis: complete guide

Overview

Liquidambar orientalis, also known as Oriental sweetgum or storax tree, is an elegant deciduous tree from southeastern Turkey and the East Aegean region. This tree is renowned for its spectacular autumn color and interesting fruit forms.

Appearance & bloom

Liquidambar orientalis reaches 26 to 40 feet tall with a narrow to broad crown form. The leaves are palmately lobed into 5 to 7 sections, similar to maple leaves. The foliage colors brilliantly in autumn with yellow, orange and deep crimson tones. In spring, small inconspicuous flowers appear followed by spiky spherical fruits.

Ideal location

Place Liquidambar orientalis in full sun for optimal fall color. A location with at least 6 hours of direct sunlight daily ensures brilliant leaf colors. The tree tolerates full sun very well and grows better in warm locations.

Soil

This tree grows best in well-draining, fertile soil. The plant tolerates various soil types but prefers slightly acidic to neutral soil with pH 5.5-7.0. Heavy clay soils should be improved with sand and compost. Ensure adequate drainage.

Watering

Once established, Liquidambar orientalis is moderately drought tolerant and requires moderate water. Newly planted trees should be watered regularly until well established. Avoid excessive moisture, especially in severe winter weather.

Pruning

Minimal pruning is required. Remove dead, diseased or crossing branches. Shape the tree in its youth for desired form. Major pruning is better done in late summer or fall.

Maintenance calendar

Spring: Inspect for winter damage. Summer: Water regularly during dry periods. Fall: Enjoy spectacular colors. Winter: Minimal maintenance, mulch young trees.

Winter hardiness

Liquidambar orientalis is hardy to USDA zone 7 (-4 to 10 F). Young trees need protection in harsher winters. A protective mulch layer around the base helps in the first few years.

Companion plants

Plant understory plants beneath the tree such as low-growing groundcovers or small shrubs. Combine with bloomers that flower in fall and winter for extended interest.
