Thanks for the info Lucy.
I do have one dwarf-it's an early bloomer and I didn't get a photo--both years I was ill when it bloomed and not up to taking photos. I would love to have some more.
"bulbus iris I. reticulate"...I am not familiar and I will research this. I have a bed of lily of the valley and ajuga(I think) that bloom simultaneously every spring--beautiful combination. Would it go well in that bed? Maybe we could transfer this discussion to Garden Chat?
