I agree ! my iris have never been happier since they have been in beds "all alone" ! Except for a few spring bulbs, and a few Asiatic lilies at the back of the beds, it's just iris. That makes culture MUCH easier for me. It helps with air-flow, sunlight penetration, and fertilizing. If you feel you need more visual interest in the "off-season", try a few of the variegated leaf iris.....Arlyn
