Native to Texas, Mexico, Colombia and Guatemala, these starry, upfacing, crocus-like flowers appear several times a season, especially after a rain, on 6″-12″ stems. The main show is generally in August-September. These pest proof bulbs don’t seem to be picky about the soil, but they are happier in full sun; will grow in pots in the water, too; 5/7 cm bulbs; 8-10 per sq. ft. For zones 4-6, try growing in pots and in the winter, keep dry and from freezing when dormant.
