Gagea serotina

Gagea serotina, synonym Lloydia serotina, is an Arctic–alpine flowering plant of the lily family. It is widespread across the mountainous parts of western North America, from Alaska to New Mexico, and in Europe is found in the Alps, the Carpathians and the mountains of Bulgaria, as well as in Great Britain. It is also native to much of Central Asia, Siberia, China, Nepal, Mongolia, Korea and Japan.

It was originally known as mountain spiderwort, but is now known in Great Britain as the Snowdon lily, or in Welsh as lili'r Wyddfa. In North America, it is called the common alplily. It is also known as Snowdon alplily.
