as the Snowdon lily, or in Welsh as ' (meaning "rush-leaves of the mountain"). In North America, it is called the common alplily. It is also known as Snowdon alplily.
Description
For most of the year, the plant is visible only as long, curving, stiff, grass-like leaves, often protruding through cushions of other plants. The flowers appear from June onwards (despite the name ''serotina'', meaning "late-flowering"), and are borne at the end of long stalks. The flowers themselves are white, with purple or reddish veins along the tepals
A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very ...
