Bearded Irises are wonderful. They are easy to grow and give you wonderful results. Bearded Irises are hardy from Zone 3 all the way to Zone 10. They do not need a chilling period so they can grow almost anywhere in the United States. It’s not uncommon to hear stories how immigrants would bring these flower with them from their home countries throughout Europe.

Key Planting Tips
Plant in full sun with 1/3 of the rhizome exposed above the soil. We like to plant ours 18”-30” apart. They fill in pretty fast. Do NOT mulch over the rhizome as they like to remain dry and extra mulch increases chances of rot. We recommended cutting the flower once it blooms to put energy back into the rhizome and the new blooms that will happen later in the summer.
Ships mid September to mid October.
