About Draba aizoides L.
Draba aizoides L. is a perennial plant that forms a basal rosette of linear, stiff, entire leaves fringed with white bristles. Its erect, hairless, leafless stems reach 10 centimetres (4 inches) tall, growing exceptionally up to 15 cm (6 in), and hold a small number of yellow flowers. These flowers have four broad, barely notched petals and four hairless sepals. This species produces elliptical seed pods. In the British Isles, Draba aizoides flowers during March and April. Draba aizoides has a wide distribution across the mountains of southern and central Europe, extending from the Pyrenees in the west, through the Alps, to the Carpathians. It also has several isolated populations in locations including the Vosges, Jura, Cévennes, Auvergne, Côte d'Or, Plateau de Langres, and the Belgian Ardennes. In the British Isles, it grows only on limestone cliffs of the Gower Peninsula, ranging from Worm's Head to Pwlldu Head. It is a lowland species that grows in soil pockets within damp cracks and crevices of limestone rocks. It rarely thrives when it grows in grassland or on bare soil away from limestone rocks.
