Harvest Tips
Bearded iris is grown primarily for ornamental flowers, not harvest. Cut stems for bouquets in the morning when the first bloom opens, cutting at a 45-degree angle and removing lower foliage. Flowers last 7-10 days in a vase with fresh water. For landscape enjoyment, allow blooms to remain on the plant for maximum visual impact.
