Pods and leaves

The perennial silver leaf ( Lunaria rediviva ), also wild silver leaf or moon violet , is a species of the cruciferous family (Brassicaceae). Together with the annual silver leaf ( Lunaria annua ) and Lunaria telekiana , it forms the genus of silver leaves ( Lunaria ).

description

The perennial silver leaf is a perennial herbaceous plant that reaches heights of 30 to 140 cm. The leaves are all stalked, pointed ovoid to heart-shaped with a serrated edge.

Dome -shaped panicles of umbrella are formed as inflorescences . The four petals are white to pale purple and 12 to 20 mm long. At night the flowers smell strongly lilac. The fruits are 3.5 to 9 cm long pods that are broadly lanceolate, compressed at the sides and translucent. Your septum is silver. Some of them stay on the plant until next spring.

The flowering period is from May to July.

The species has chromosome number 2n = 30.

ecology

The perennial silver leaf is a perennial hemicryptophyte and a half-rosette plant with a rhizome .

The flowers are large, fragrant "plate flowers" with protruding anthers. The calyx tube is quite long with 8–9 mm. The nectar is enriched at the base of the stamens . Pollinators are moths and bees , as well as pollen- eating insects . The flowers are probably self-sterile . The flowering period is from May to July.

The pods shed their fruit flaps when they are ripe. In addition to the seed-bearing frame, what remains is the false partition as a conspicuous structure. This serves as a wind catcher and promotes the spread as a wind spreader. The seeds with a skin border are glider pilots and cold germs. Fruit ripening is from August to October.

Occurrence

The perennial silver leaf occurs from the Iberian Peninsula across Central and Southern Europe to the European part of Russia and southern Sweden. It thrives on seep-fresh, nutrient-rich and base-rich, agitated, loose, moderately acidic to mild, humus-rich, fine-earth rubble soils such as lime, basalt, porphyry or gneiss. It occurs mainly in moist, shady deciduous mountain forests in warm and winter-mild locations in humid climates. It is a character species of the ash-maple canyon forest (Fraxino-aceretum).

use

The perennial silver leaf is occasionally planted as an ornamental and scented plant.
