Pollination and foliage
Salix viminalis is diocesan. In addition to cross-pollination, wind pollination is also possible. The alternately arranged leaves have a smooth leaf margin, a simple leaf structure and a lanceolate leaf shape. The green flowers bloom in March and April.
Salix viminalis prefers deep soils in the catchment area of aquatic ecosystems. The chosen soil should also be calcareous and rich in nutrients. Under optimal conditions, an extremely bushy growth occurs. Salix viminalis also grows on slightly arid soil. However, the growth results cannot compete with the results obtained on humid soils.
The wicker can be found all over Europe with the exception of Scandinavia. Due to anthropogenic influences, Salix viminalis found its way into the ecosystems of the British Isles. There the branches of the wicker were used to make baskets. The osier is also found in North Asia.
Salix viminalis knows how to convince with its diverse uses. In this way, the hardy wicker can easily be used as a base. It also serves insects as a nectar and pollen plant, thus taking on the function of the insect nutrient wood. As an example, a total of 21 butterfly species are to be set at this point. Due to its preference for humid soils, Salix viminalis is ideally suited for enhancing aquatic ecosystems. These include in particular the bank areas of rivers, ponds and lakes. In such ecosystems, Salix viminalis can also serve as bank reinforcement.
