The "iris tectorum" plants I grew from seed in 2008 finally bloomed - and I don't think they are what they were advertised to be (seed from a different society exchange). They look more like the Siberian irises in our garden than online photos I consulted of I. tectorum. Any other opinions?
Rob, I'm not an Iris expert by any means, but it does look like Siberian Iris to me too. At a garden tour a couple years ago I was surprised at just how fine I. tectorum was, the garden visited had the white form. My plant shown here is only in its second year after a purchase, but its making a good show of exquisitely shaped flowers, I must move this to a more prominent location in the garden.
