For best results, sow outdoors in late fall in a well-drained, sunny area. Start indoors two to three months before last spring frost. Seeds started indoors and sown in spring must be cold treated (stratified) for proper germination. Place in cold, moist, sterile potting soil in a dark place, or between moist papers towels in a plastic bag stored in the refrigerator for six to eight weeks before planting. Soak refrigerated seeds in warm water for 24 hours before planting.

Remove faded flowers to encourage more blossoms. Fertilize sparingly.
