Forsythia, which is often planted as an ornamental shrub and is also a member of the olive family, is in bloom in many places. However, as it is mainly pollinated by insects, its pollen is rarely released into the air in large quantities. Nevertheless, allergy sufferers should refrain from using flowering forsythia branches as decorations in their homes in order to keep indoor spaces as allergen-free as possible.

In the Ländle region, forsythia blossoms along flowing and standing waters willows and poplars. Both are closely related and can cause allergic reactions in sensitised people. The palm catkins of the Sal willow can also cause stress in their environment.
