Harvest Tips
Cut flowers at stem base in morning for longest vase life. Flowers are excellent for fresh and dried arrangements. Leave some flowers on plant to mature for seed collection in fall (seeds will self-sow). For drying, cut when fully open and hang upside down in a warm, dry location for 2-3 weeks.
