The downy birch is also called hair birch, broom birch and glass birch. Botanists refer to them as Betula pubescens. It can grow to heights of up to 20 meters and widths of up to 12 meters. Betula pubescens comes with a white and black bark typical of birch species and an upright growth.
Pollination and foliage
Betula pubescens is monoecious. Both cross-pollination and wind pollination can be defined as types of pollination. The green and yellow flowers bloom in April and May. The egg-shaped and pointed leaves delight the viewer in spring and summer with a dark green color. In addition, the downy birch can come up with nut-shaped fruits.
Betula pubescens is happy about clayey and sandy soils with a low nutrient content. The downy birch is a real delight with significant soil moisture and a sunny location. However, you shouldn't expect it to have a high lime content.
Betula pubescens is found on the old continent and in Asia. It can be found there especially in the moors. Your common name indicates this. However, it can also be found in more mountainous regions. In the alpine area you can find stocks at an altitude of up to 2,000 meters.
Betula pubescens can come up with several uses. Due to its beautiful growth, it cuts a particularly good figure in gardens and parks with a moist soil variation. The downy birch is particularly suitable for the vegetation-ecological upgrading of bog-like and boggy forest ecosystems. In newly established stocks, Betula pubescens takes on a so-called pioneering function relatively quickly. Due to the association with the silver birch, rowan, quivering poplar and common ash, the creation of such a planting association can be recommended. In this way, species-rich forest ecosystems can be established on a suitable soil variation. When planning a new forest ecosystem, we are happy to provide you with competent advice on all matters.
