Description

The Spring starflower is a bulbous perennial in the amaryllis family (Amaryllidaceae) native to Argentina and Uruguay. The specific epithet means one flower.

Spring starflower prefers a sheltered, sunny position in average, well-drained, slightly moist garden soil. During summer dormancy, the soil can be drier. They will readily spread by bulb offsets and seeds. Plant bulbs 2 to 3 inches deep and 2 to 4 inches apart in the fall.

In early to mid spring, spring starflower produces masses of individual nearly white to violet-blue star-shaped flowers on 6-inch scapes. The foliage is grass-like and has an onion-type aroma when crushed.

Use this plant in borders, rock gardens, along walkways, around shrubs or naturalized areas.

Quick ID Hints:

  • Grass-like leaves have a garlic/onion scent
  • Produces 6-pointed bluish white star flowers in spring.
  • Tepals have a darker central vein on the underside.
  • Has numerous scapes of solitary flowers.

Insects, Diseases, and Other Problems:   No significant problems.
