The urban land potential for increasing biodiversity through functional and perennial seeding is not yet sufficiently explored. Seeding in urban areas must meet different requirements. Among other things, they should be easy to care for and visually attractive, but not too tall so as not to impair the lines of sight in road traffic. In addition, they must be able to cope with the hot, dry urban climate and nutrient-rich soils. Flowering until late autumn is desirable for providing nectar and pollen throughout the season.
These requirements are difficult to meet with native mixtures, so mixtures with alien species have to be investigated for their suitability in urban areas and their usefulness for arthropods, as well as for interactions with urban trees. The aim is to gain knowledge about the value of plants of foreign origin as nectar and pollen source in comparison with native species or lawns and their suitability for urban areas in the interaction between sown areas and trees on them.
