Description

Populus x berolinensis (Berlin poplar) was discovered in 1865 in the Berlin Botanical Garden as a spontaneous cross between Populus nigra ‘Italica’ and Populus laurifolia. The hybrid grows a straight, continuous trunk that barely bifurcates. Its steep upright branches create a columnar crown that turns into an oval at an older age. The bottom branches hang down, giving the tree a width of 10 metres. It reaches a height of about 25 metres.

As one of the earliest trees to bud, Populus x berolinensis is a striking image in the spring. Its ovoid leaves are bright green with a grey-green underside. It has a sharp top. Its autumn colours, with green and yellow hues, are not particularly striking. There are male and female trees, both of which bloom green catkins. The female trees disperse cotton-like seeds from the capsules.

The Berlin poplar is very good at tolerating wind, air pollution and drought, and does not require much of the soil. The tree does prefer moist soil. Populus x berolinensis is a perfect tree for both urban and rural uses, e.g. in parks and central reservations, but also as an avenue tree in a broader profile. The species is relatively sensitive to leaf spot and prone to poplar rust, but not very sensitive to bacterial canker. The trunk grows shoots until it is very old.

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.
