Black Hills Gold has some absolutely HUGE flowers on a very tall stem, first year after planting. Definitely one of my favorites.

This is such a pretty iris! It is a clear yellow diffusing into a light flush of pink -- it is aptly named. I have it growing next to a sidewalk in dappled sunlight where most of my other irises have died. This one continues to come through for me. One of my favorites.
