During my last 16 years of bulb hunting, I've mostly heard these called the woodland painted petals. The coral colored flowers bloom in March to April for us while the white ones bloom for us in northeast Texas in mid May. By June the foliage has disappeared. I've also seen this around Houston growing aggressively on some of the old homesites. They are small bulbs but they pack a punch! Many folks call them Freesia laxa 'alba' but they've also been labeled Lapeirousia laxa ‘Alba’ orAnomatheca cruenta, but we're going to stick with the Missouri Botanical Garden classification of Anomatheca laxa 'alba.'
Blooms: These little flowers are a clean, glowing white, sometimes with faint markings at the base of the lower petals, held in small sprays on stems about 6-12 inches tall above fans of bright green, sword-shaped leaves. The white ones bloom for us in northeast Texas in mid May, and they reseed readily, so a small planting soon becomes a carpet of white.
Planting: These come to you growing in 4-inch pots, so plant each one at the same level it is growing in the pot, about 4-6 inches apart. If you are planting dormant corms, set them about 2 inches deep. They do best in part sun to dappled shade (think the edge of a woodland garden) in well-drained soil, and they do not like to sit in soggy soil, especially while they are dormant in the summer. Fall is the ideal time to plant. They are perennial in zones 8-10.
After Blooming: By June the foliage has disappeared and the corms rest through the summer. Let the foliage die back naturally and let the seed pods ripen if you want them to spread; new seedlings will pop up the following year.
Landscaping Tip: Tuck them under deciduous trees, along shady paths, or at the front of a border where their small flowers can be seen up close. They are also charming in containers and pair nicely with spring bulbs like snowflakes and jonquils.
