ZONES: The rebloom zone noted in the description is the lowest (or coldest) zone in which the iris has been noted to rebloom, and it has rebloomed in all higher zones. For example, "Rebloom to zone 4" means that this iris reblooms from zones 4 - 10, but not zones 1, 2, or 3. For more detailed information see our Glossary
In addition to blooming in the Spring, the reblooming bearded iris plant have the ability to bloom again in the Summer and Fall. They are called Reblooming Irises. Fall bloom cannot be guaranteed. It depends on the combination of location, climate, and amount of water. The reblooming Iris plant will require more watering in the warmer climates. They should be watered once a week without rainfall.
We have one of the largest collections of reblooming Irises you can find.
There are hundreds of varieties of reblooming Irises to choose from.

The reliability information is based on our gardens in San Jose and the growing fields. The growing fields are zone 8 and the viewing gardens are in zone 8. The zone numbers are the lowest (coldest) zones that reblooms have been reported. An Iris with a zone 6 should be able to rebloom in zones 6 and up.
