Colorful Giant Crocus are one of the first signs of spring. Perfect for borders or edging. Group them by the dozen, or hundreds and thousands for naturalizing in the grass, woodlands, slopes, or under trees. Crocus can be successfully grown in a lawn for a spring meadow effect. Plant in fall in well-drained, sandy soil in full sun to partial shade. The colors range from white, yellow and striped to lavender and deep purple.
