The beautiful bindweed ( Calystegia × pulchra Brummitt & Heywood ) belongs to the bindweed family (Convolvulaceae). It is the hybrid Calystegia pellita × Calystegia silvatica .

Identifying features

It is a perennial herbaceous plant . It climbs about 1 to 3 meters high with the twisting shoot. The petioles and flower stalks are partly hairy, and the stem can also be hairy. The beautiful bindweed is particularly noticeable for its pink colored crown, which has 5 white stripes, is about 4 to 6 cm long and just as wide. It can be distinguished from the very similar real bindweed by the vesicular distended calyx before leaves.

The number of chromosomes is 2n = 22.

distribution

The origin of the beautiful bindweed is unclear, Haeupler and Muer state Northeast Asia as their home, Oberdorfer writes “maybe East Asia”. The species is not recorded in the “Flora of China”. In the "Rothmaler", on the other hand, Western and Central Europe is named as home, in R. Govaerts "Europe". It is rarely found as an ornamental plant.

In Europe they can be found in alluvial forests and brooks, as well as in fresh ruderal locations and herbaceous fields. It prefers nutrient-rich locations. She naturalized herself as a neophyte in societies of the Galio-Urticenea subclass. In the Allgäu Alps, it rises in Oberjoch in Bavaria to an altitude of 1150 meters.

ecology

The beautiful bindweed is one of the creeping pioneer plants because of its deep creeping, underground shoot axes . The tips of the shoots perform circular search movements ( nutations ) in an anti-clockwise direction in order to be able to wind up on a suitable base. The pollination is mainly by butterflies.
