Flounder Birch (Betula verrucosa)
| Occurrence in Děčín |
It grows in many parks. The most beautiful specimen can be found on the meadow near the gardening colony in Hluboká Street, the trunk circumference is 250cm. |
| Application |
Important for landscaping, especially as a pioneer light-wood. In urban parks it is used for early growth for the early effect of tree matter; he later gives way to skeletal trees. Nevertheless, it has an irreplaceable role in establishing heathland communities with pine and juniper. Great coverage can be achieved when planting birches into a group with dogwood - a combination of white and red bark stands out especially in winter. It has many cultivars that stand out as solitaires. |
| Habitat |
Grows from lowlands to 2000m. It is well tolerated by drought and so we often find mixed forests in the rocks with pine and some with juniper. It requires light habitats, is resistant to frost and exhalates. In the shade of the mighty trees he dies.
