A true harbinger of spring, it can be planted in borders, rock gardens, and even lawns. After flowering, the foliage must be left intact until it withers, which may cause lawn-mower anxiety in some gardeners. Often sold as "mixed crocus," cultivars of this species are typically white, lilac, or purple and white striped. Noteworthy Characteristics: Very early blooming; naturalizes in lawn. Care: Provide full sun to light shade and average, well-drained soil. In fall, plant corms four inches deep in groups of six or more. Lift and separate them after four or five years, discarding the mother corm. Propagation: Divide every four or five years. Problems: Nothing serious, but squirrels and mice may eat the corms.
