Harvest Tips
This is an ornamental shrub not harvested for culinary use. Cut flowers for arrangements during peak bloom season (spring-summer) by snipping stems with sharp pruners. Flowers last 1-2 weeks in a vase. For propagation, collect seed capsules in late summer-fall after they dry; seeds germinate best with light scarification.
