This is a collection of Bearded Iris we have found perform very well as a cut flower. With strong stems and well-spaced buds.
Cut the stem, at the base near the rhizome, when you see the first flower start to unfurl.
Display your iris out of direct sunlight and change the water every 3-4 days. Recut the stems if necessary and pinch off the wilted flowers as more blooms emerge lower down the stem.
