This amazing iris bloomed for us the very first year we had it. We bought six bulbs and each bloomed with lovely pearly pink and creamy white gorgeousness. This iris is from 1983, and it became a historic this year, as it will be 30 years old. Goes really great with other amoenas and especially with dark purples like Helen Collingwood. We also would recommend this iris to anyone. It's color is like no other iris, their is just something that stands out, and is special about it. It will always be a favorite of ours.

I bought this one at the nursery while it was in bloom. I had never heard of it, but loved the colors. It has bloomed for me each year and has survived and multiplied with out much attention from me. I would recommend it.
