Some things to know before you start: first, irises are clonal, which means each child plant is a genetic duplicate of the parent plant. Because irises don’t mutate often, nor do they create seeds easily, we can grow the identical irises that our great-grandmothers grew. Irises are truly “living history.” What a fascinating thought!
There are over 70,000 registered bearded irises, all of them unique. Many have long since disappeared, but many historic irises remain. HIPS defines a “historic iris” as one that has been commercially available for at least 30 years. Many historic irises date to the mid-1800s or earlier. Let us show you how to grow them yourself!
