>If Iris spuria Caitlin's Smile is as I think, a selection of a >species,could someone reveal the correct botanical designation of this >cultivar please? Dear Peter, If the iris you refer to is 'Caitlin's Smile' then it is 'Caitlin's Smile' (James Waddick by Kevin Morley). This means it is my seedling, but named and registered by Kevin. This is a pure Iris typhifolia, a relatively newly introduced Siberian Iris species, not a spuria iris. It received an Award of merit in 2011. Incidentally both Kevin and I have daughters named Caitlin. It blooms very early. Hope you are enjoying it. Best Jim W. -- Dr. James W. Waddick 8871 NW Brostrom Rd.
