The Story

Plant Bio

Liquidambar styraciflua is a large, deciduous tree native to North America, prized for its star-shaped leaves and spectacular, long-lasting fall color. The species is known for its spiky, gumball-like fruit.

'Rotundiloba' is a unique, sterile (fruitless) cultivar with distinctive rounded lobes on its leaves instead of the typical pointed ones. It offers the same brilliant fall color without the messy fruit.

Uses & Benefits:

This is a premier shade tree, offering beautiful, uniquely shaped glossy green leaves all summer, followed by a breathtaking, long-lasting display of yellow, orange, red, and purple fall foliage. Its fruitless nature makes it a clean, low-maintenance choice.

As a large, long-lived tree, it provides significant shade and cooling for homes and public spaces. Its upright, pyramidal form makes it an excellent choice for lining streets and avenues without the hazard of its spiky fruit.

The tree is a host plant for the Luna moth and other native insects. Goldfinches and other birds eat the seeds of the species, but this cultivar is sterile. It still provides valuable canopy cover and nesting sites.

Water deeply and apply a 3-inch layer of mulch.
Keep consistently moist for the first few years to establish.

Pro Tip
