I grow Iris cycloglossa in a pot with my other (mostly easy) juno irises. BUT this species flowers weeks after the others. In my experience it needs watering and feeding (I use liquid feed) for much longer in spring than the other taxa. From one seedling a few years back I now have 4 noses poking through the top dressing so I hope to try it outside soon. Tony Goode. Norwich UK. Mintemp -8C
