Description

Liquidambar styraciflua ‘Paarl’ (American sweetgum ‘Paarl’) was selected by Lappen Nurseries in Paarl, South Africa in 1990. The tree grows to be 20 metres tall and has strong, vertical branches, creating an upright columnar to narrow pyramidal crown. When it is older, the branches start to droop, which is likely due to its rich fruit production. 

The American sweetgum ‘Paarl’ blooms discrete, yellow-green flower heads in April. The thick, pentalobate leather-like leaves bud bronze and turn a dark green with yellow veins in summer. Its autumn colours appear quite late in autumn. Depending on its environment, its autumn leaves are a lovely gradient from dark yellow to yellow-orange and from orange-red to green-violet. The spiky brown capsules the tree produces in autumn are small, but striking. In contrast to the main species, Liquidambar styraciflua ‘Paarl’ does not grow cork on the trunk and branches. 

Its thin habit and solid wind tolerance make the ‘Paarl’ cultivar a great tree for streets and avenues. It can handle pavement and air pollution very well, which makes the selection perfect for use in industrial locations. The tree’s abundant fruit production can be seen as a downside in some locations. Liquidambar styraciflua ‘Paarl’ does best in nutrient-rich, moist soil with an acidic to neutral pH value. Plant the tree in a sunny environment for the most beautiful autumn colours.

Winter hardiness

A plant's winter hardiness is the coldest area in which it is frost-resistant. This is based on the average annual minimum temperature. Winter hardiness zones are thirteen different frost zones in steps of 5.5 degrees Celsius. This format is an international standard for the hardiness of plants. The zones in which the plant is frost-resistant are always included in the description of trees and other vegetation.

Winter hardiness is a genetic characteristic and is not influenced by the location in which the plant is cultivated. This means that a plant that has been cultivated for many years in winter-hardiness zone 6 but has a winter hardiness of 3 is perfectly suited for replanting in a colder zone. It will thrive there thanks to its genetic characteristics.

When choosing planting for a project, the winter hardiness of the plants is extremely important. By choosing species that match the zone in which the project is being created, it is possible to ensure that plants can withstand the minimum temperature in that area.
