Where irisarians bloom together
We are a group of iris enthusiasts, hybridizers, and avid gardeners dedicated to inspiring a love of the genus Iris — through cultivation, propagation, and the art of hybridizing.
Based in the shadow of Mt. Diablo in Contra Costa County, we bring together gardeners, hybridizers, and nature lovers who share a passion for one of the world's most elegant flowers.
Whether you're a first-time grower or an experienced hybridizer, you'll find a welcoming community here — with knowledge to share and irises to admire.
