Vegetative characteristics

The edged leek is a perennial herbaceous plant that usually reaches heights of 20 to 35, often up to 50 centimeters. The leafless stem is angular to sharp-edged towards the top. The flat, narrow-linear and basal leaves are, unlike vineyard leeks , sharply keeled on the underside. No bulbs are formed.

Generative characteristics

The flowering period extends from July to September. The flowers stand together in dense, shawny inflorescences . The hermaphrodite flowers are threefold. The six tepals are light purple in color (rarely white).

The number of chromosomes is 2n = 16.

Occurrence and endangerment

The edged leek occurs in Central and Southern Europe to Western Siberia , it is absent on the British Isles and in Northern Europe from Denmark. In Germany it can be found widespread to scattered, in the north and northwest it is completely absent.

In the entire distribution area it is rare and is considered endangered.

The edged leek is considered a pointer plant of changing groundwater levels, as it endures a temporary drying out of its locations during the summer. The edged leek grows in wet meadows , on river and lake banks and in rushes . The edged leek thrives best on humus-rich and loamy but nitrogen-poor soils . It is a Cnidion association character in Central Europe , but also occurs in societies of the Molinion association and the order Phragmitetalia.
