Description

The Spring Starflower is a bulbous perennial that grows up to 10" tall. This South American ground cover tolerates drought but should be kept moist during the growing season. In early spring, its bulb produces grass-like foliage and multiple flowering 6" stems with single white to violet-blue star flowers. 

The plants grow in sun to partial shade, become dormant after blooming, self-seed and bulb offset to spread leading them to be useful in naturalizing lawns and under trees. This plant prefers a sheltered, sunny position with slightly moist soil.  Both flowers and foliage are mildly fragrant. Plant blooms in early to mid spring and produces masses of flowers on individual scapes. This plant spreads if left undisturbed. Plant in late fall and bury plants 5 in. to base of the bulb and space 2-4 in. apart, 10-20 bulbs per sq. ft.  These are excellent for use in rock gardens, lawns, and woodland gardens.

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.
