Harvest Tips
White Anthuriums are ornamental flowers not harvested in the traditional sense. Cut flowers for arrangements when the spathe is fully open and the spadix has begun to yellow slightly. Remove at the base of the flower stalk using a clean, sharp knife. Cut flowers can last 2-3 weeks in water, making them excellent for long-lasting floral displays.
