Harvest Tips
Deadhead spent flowers regularly to promote continuous blooming throughout spring. Harvest flowers at peak bloom in mid-morning after dew dries. Allow some flowers to mature if collecting seeds; harvest seed capsules when they turn brown and dry, then let them dry fully before extracting seeds. Cut flowers last 1-2 weeks in water.
