I love this style of flower. It's a nice sturdy plant and a good tall stalk.

People generally either love or hate broken color irises. My husban loves them. I find them very intriquing also. This one took 3 years to come into glory, but the wait was worth it. What a beauty it has been for the last 2 years. Even though it is suppose to grow only 30 inches tall, we have ours on an elevated mound. Ours still grows about 34 inches tall, even without the mound.
