About Arabis eschscholtziana Andrz.
Arabis hirsuta, commonly called hairy rock-cress, is a flowering plant that belongs to the Brassicaceae family. In older North American botanical publications, this species was broadly defined to include plants native to Europe, Asia, and the northern half of North America. Modern classification now more often restricts the species to a narrower group of plants found only in Europe. Arabis hirsuta can grow up to around 75 centimetres (30 inches) tall. It is typically unbranched, and bears a long spike of flowers. Lower leaves form a rosette, while the stalkless upper leaves clasp the stem. Its white petals are twice as long as its sepals, and it flowers from June to August. The fruits of this species are cylindrical and pressed closely against the stem. Its slightly winged seeds are reddish brown in color. This plant has stiff, forking hairs. It grows in habitats including chalk slopes, dunes, hedgebanks, walls and rocks. As of 2021, the conservation status of Arabis hirsuta in the United Kingdom is classified as "least concern".
