Acis rosea
Acis rosea, known as the rose snowflake,[2] is a species of flowering plant in the family Amaryllidaceae, native to Corsica and Sardinia.[1] Unlike most members of the genus Acis, it has pink rather than white flowers. It is grown as an ornamental plant but requires protection from frost. DescriptionAcis rosea is a small bulbous perennial, growing up to 12 cm tall. The grey-green leaves are narrow and usually appear after the flowers. Flowering occurs in autumn. The flowers are small, 5–9 mm long, and have pink tepals – most other species of Acis have white tepals. The pedicels (flower stalks) are short, 1–5 mm long. There are two spathes.[2][3] TaxonomyAcis rosea was first described in 1804 by F. Martin, as Leucojum roseum. In 1829, Robert Sweet transferred it to Acis.[1] However, Acis was not accepted by most botanists, who continued to use a broadly circumscribed Leucojum.[2][3] Acis was reinstated in 2004, after it was determined on morphological and molecular grounds that the broadly defined genus Leucojum was paraphyletic.[4] Distribution and habitatAcis rosea is native to the two western Mediterranean islands of Corsica and Sardinia. It is found in rocky ground, dry pastures and sandy places.[2][3] CultivationAcis rosea is cultivated as an ornamental bulb. As it is not frost-hardy, it is usually grown in a bulb frame or alpine house.[2][3] References
