About

Leucojum vernum, commonly called the spring snowflake, St. Agnes' flower (for the patron saint of virgins), 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.

The Latin specific epithet vernum means "relating to Spring"; its close relative, Leucojum aestivum, flowers in summer.

How to grow it

Leucojum vernum is cultivated as an ornamental plant for its white flowers in spring. It is described as "easy to grow", either in sun or partial shade, particularly in moist soil and in grass. The species has gained the Royal Horticultural Society's Award of Garden Merit.

Safety

All species of Leucojum are poisonous as they contain the alkaloids lycorine and galantamine.
