Plant Common Name

Spring Starflower, Springstar

General Description

This small, colonizing, cold-hardy bulb from south-central South America produces carpets of starry flowers early in the year.

The thin, grassy, green to gray-green leaves appear in fall. In late winter and early spring, six-petaled, pale lilac-blue flowers are borne singly on short stems, attracting bees or early season butterflies. The garlic-scented foliage disappears in summer. Plants spread vegetatively and by seed to form large drifts.

Grow this charming bulb in full to partial sun in fertile, well-drained soil that is moist in spring. Plant it in informal clumps in the mixed border, cottage garden, wildflower meadow, or rockery. It is a traditional flowering bulb allowed to carpet lawns in the American South. Selection 'Alberto Castillo' has large white flowers and relatively broad gray-green leaves; 'Froyle Mill' produces powdery amethyst-purple flowers; and 'Wisley Blue' bears light blue-lavender blooms. It is not eaten by deer, squirrels or voles.
