Leucojum vernum

About

Leucojum vernum, commonly called the spring snowflake, St. Agnes' flower, and rarely snowbell among others, is a species of flowering plant in the family Amaryllidaceae. It is native to central and southern Europe from Belgium to Ukraine. It is considered naturalized in north-western Europe, including Great Britain and parts of Scandinavia, and in the US states of Georgia and Florida. This spring flowering bulbous herbaceous perennial is cultivated as an ornamental for a sunny position. The plant multiplies in favourable conditions to form clumps. Each plant bears a single white flower with greenish marks near the tip of the tepal, on a stem about 10–20 cm (3.9–7.9 in) tall, occasionally more.
