description

blossom

The nodding milk star is a perennial herbaceous plant with heights of usually 30 to 50 (15 to 60) centimeters. This geophyte forms onions with a length of about 2 to 3 cm and a diameter of about 2.5 to 3.5 cm, which forms many brood onions. The mostly four to six, rarely three, arranged in a basal rosette leaves are simple, parallel-veined, linear and up to 60 cm long.

In the late winter, the nodding Milky Star begins photosynthesis and blooms between mid-April and early May. On a leafless stalks standing traubige inflorescence with usually five to twelve (rarely up to 18) flowers. The bracts are 3 to 4 cm long. The nodding flowers are threefold and hermaphrodite. The six bell-shaped fused bracts are white with a green stripe on the back, 20 to 30 mm long and 9 to 12 mm wide. The three inner and three outer bracts are shaped slightly differently. Of the six stamens, the outer 6 to 8 × 3 to 4 mm, the inner 13 to 15 × 4 to 5 mm. The stamens are winged (toothed). The anthers are 3 to 4 mm long. The slightly six-winged ovary and the style are each 5 to 6 mm long. The capsule fruit is broadly ovate. After flowering, the leaves dry up and the bulb survives the dry summer months underground.

Occurrence

The nodding milk star comes from western Turkey, Bulgaria and eastern Greece, but the species is now wild in many parts of the world. In the baroque era , the milk star was planted in Europe as an ornament for palace and monastery gardens. That is why it occurs today in the vicinity of these facilities (bushes, fields, vineyards). It is locally a character species of the Geranio-Allietum from the Fumario-Euphorbion association, but also occurs in societies of the Alliarion association.

However, it is relatively rare in all of Germany. In the garden of Paretz Palace near Potsdam , the nodding Milky Star became a small attraction during its heyday; The literary and cultural effect of the plant is explained in guided tours using the example of the text "Nodding Milky Star" by Ludwig Sternaux . The state of Saxony has the highest population of the nodding milk star in Germany, where it grows, for example, on the Roitzschberg near Meißen and at Pillnitz Castle near Dresden.

In Austria it is mainly found in the eastern, Pannonian regions. This is also the case in northern Lower Austria around Altenburg Abbey .

In Switzerland this species occurs sporadically in the area around Schaffhausen , in the Rhine Valley and in the area between Bern and Thun; but there it is considered endangered.
