The Story
Plant Bio
Liquidambar styraciflua is a deciduous tree native to North and Central America, producing palmately five-lobed, star-shaped leaves that turn yellow, orange, red, and burgundy in fall. Inconspicuous yellow-green flowers appear in spring before maturing into spherical fruit capsules.
'Slender Silhouette' forms an exceptionally narrow, fastigiate column reaching up to sixty feet tall while spreading only three to six feet wide. Its ascending branches closely hug the main trunk and lack corky ridges, dropping drastically fewer prickly fruit capsules than the species.

Planting
How to Grow
- Choose a site in full sun with deep, moist, well-draining acidic to neutral soil.
- Dig a planting hole twice as wide as the root ball and at the same depth as the soil line.
- Backfill with native soil, press firm to eliminate air pockets, and water deeply.
- Apply a two-inch layer of organic mulch around the base, keeping it clear of the trunk.
Pro Tip
Avoid heavy nitrogen fertilization, as forced rapid vertical growth causes the tight columnar structure to split open.
Keep It Thriving
Care Guide
Do
- Plant in full sun to maintain tight vertical growth and bright fall leaf color.
- Provide regular moisture while the tree establishes its root system.
- Ensure soil remains acidic to neutral to prevent iron chlorosis.
Don't
- Do not plant in highly alkaline soils.
- Do not cut back into old leafless wood lacking dormant buds.
- Avoid applying heavy nitrogen fertilizers that induce structural splitting.
