I have had this plant for 10 years... it bloomed once, in 2001, and I was lucky enough to capture it. My father knew what it was, but I can't remember what he told me. Anybody know what this is? Thanks for any help!
It's definitely a species of Neomarica, a South American Iris relative, probably Neomarica northiana. Sometimes called "Walking Iris" because new plantlets sprout from the inflorescence and take root when it bends down to the ground.
