Crocus vernus Blue Moon Mixture is a striking combination of purple, blue and white bulbs. Blue Moon Mix Crocus naturalize easily and look lovely planted into a lawn. These large flowering Crocus are easy to grow in well-drained soil in full sun or partial shade. They are also a perfect bulb for forcing indoors. If planting in the lawn wait at least six weeks after the crocus have flowered to mow the lawn. Crocus will multiply and come back year after year if left undisturbed. Plant in fall to a depth of 3 inches.
