Arabis hirsuta aka Hairy Rockcress
Taxonomy ID: 8634
Arabis hirsuta, commonly known as hairy rock-cress, is a member of the Brassicaceae family and is native to Europe, Asia, and the northern half of North America. However, it is now more commonly restricted to a narrower subgroup found only in Europe. This hairy plant is erect and typically unbranched, growing to a height of 15-60 cm (6-18 inches), with a long spike of flowers that bloom from June to August. The lower leaves form a rosette, while the upper leaves are stalkless and clasp the stem. The white petals are twice as long as the sepals, and the seeds are reddish-brown and slightly winged. The plant's hairs are stiff and forking. Arabis hirsuta grows on chalk slopes, dunes, hedgebanks, walls, and rocks. In the UK, its conservation status is near threatened as of 2001.
Eschscholtz's Hairy Rockcress, on the other hand, is a super rare houseplant that needs regular watering to thrive. It prefers long-lasting, direct light and should be kept less than 1 foot from a window. This plant likes soil that is well-draining. Although this description is for Eschscholtz's Hairy Rockcress, it is important to note that it is a different species from Arabis hirsuta.
