Description

xSycoparrotia semidecidua ‘Prins Claus’ (sycoparrotia ‘Prins Claus’) is a selected intergeneric hybrid between Sycopsis sinensis and Parrotia persica. This tree was developed by Professor Henry Gerhold at Pennsylvania State University, United States, and introduced and named in the Netherlands by nurseryman P.L.M. van der Bom. This selection remains narrower, grows more slowly, and retains its leaves longer into winter than the standard xSycoparrotia semidecidua. As a young tree, ‘Prins Claus’ has a pyramidal growth habit; with age it develops into a dense, broadly ovoid crown reaching about eight meters in height and two to four meters in width.

‘Prins Claus’ is semi-evergreen. The leaves are shed only in late February, just before new foliage emerges in March. When the tree is briefly bare, red Hamamelis-like flowers appear. On closer inspection these consist of small clusters of red stamens with yellow pollen, enclosed by brown perianth segments. Fresh foliage follows in bright green tones, turning glossy dark green with a leathery texture during summer. In autumn, the leaves change color from green-yellow to deep yellow and orange. The bark of xSycoparrotia semidecidua ‘Prins Claus’ is light gray and smooth, while the branches are darker gray.

From an ornamental perspective, this selection is a striking addition to urban landscapes. In terms of health and vigor, it is an exceptionally strong tree. xSycoparrotia semidecidua ‘Prins Claus’ prefers a moist but well-drained soil ranging from neutral to acidic. Pavement and air pollution pose no problems, and its modest size and growth rate make it an excellent, disease-free street tree. Because it is semi-evergreen, it also provides attractive year-round screening in gardens. When young, proper formative pruning is necessary to establish a good tree shape. However, due to its compact cell structure, trunks with a circumference of sixteen to eighteen centimeters are already extremely sturdy and difficult to break.

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.
