About

Glacier buttercup is a plant of the Arctic and the highest mountains: it grows in Spitsbergen, Greenland, Alaska, and in the mountains of Europe — in the Alps and Tatras. In Poland, it occurs only in the Tatras and rarely. Our records come from the High, Western, and Low Tatras; half of them are above 2000 m. This species is absent in Ukraine.

The plant is 5–15 cm tall. The stem is thick and juicy, bare, upright or sprawling. The leaves are evergreen, glossy, fleshy, 1–4 cm long. On the stem, there are one to three flowers with petals 9–15 mm; contrary to the name of the genus, they are not yellow, but white or white-pink.

It blooms from June to August. It grows only on granite: in rock crevices, often on nearly vertical walls, on ledges, screes, and stone debris, from the juniper belt to the highest rocky peaks. According to Polish Wikipedia, the species generally rises to 4250 m above sea level.

Like many buttercups, it is poisonous — it contains ranunculin. The plant is rare, growing in national parks where picking anything is prohibited; it is best viewed up close in photos.

This species does not live in the Ukrainian Carpathians today — you can see it in other Carpathian countries.
