This is my first, and maybe my only iris to bloom this year. I love this one with it's beautiful lavender color and grape soda fragrance, but I'd love to have more blooms.

I have different kinds in different places throughout my yard and none do well. Any help with how to get more blooms? They don't seem to need thinning. Some are singles.

A different kind, maybe Indian Chief. I tried moving these a few years ago. They were a little closer to the fence. I've also tried mulching.
