Interesting about the robinia
The genus of Robinia (Robinia) includes about 20 different species. Until the 17th century, Robinia were only native to North America, but have now been spread by humans in all parts of the world (apart from Australia and the Antarctic). And that is now a problem, because the robinia is superior to many native trees. It displaces other tree species by a long-term change in soil conditions. Due to the symbiosis that Robinia roots undergo with nitrogen bacteria, there is an increase in nitrogen content. In the end, the robinia thus creates its own favorable soil conditions and at the same time worsens the ecological conditions of other trees, which makes them overgrow other trees in the long term.
A full-grown Robinia tree can easily form tens of thousands, depending on the species white to pink, flowers. These hang on up to 30cm long inflorescences and are not least because of this enormous mass of flowers an important nectar donor for insects. Because of the comparatively similar form of leaves to the acacia plants, robinia are also called translucent acacia designated.
