Valerie, perhaps, then you'd quite possibly have to go with a Japanese Iris, or Siberian ? As, all I could find at Vesey's in Canada, is 'About Town' & that the season is listed, as early to mid season.. But.please do keep in mind, this is Richard's Thread, (about 'Dusky Challenger' in particular..) Not that I haven't ever posted on threads & have been known to "Ramble On' ! lol Check 'Ensata Gardens' website.
