Yes, the Muggles are a very rich yellow. The first day 5 opened all together, and it was such a pretty display. They stand out in a garden.
And I agree about Golden Snitch Bonnie, but it has to get a bit less expensive before it gets to my garden! Maybe next year.....
All this talk about color reminds me. I have been trying a couple of days now to capture the true color of three other SDB's that have opened. So for those, waiting on the rest of the Guise picks, I want you to know that it is tricky to capture how amazing the color combination is on that iris.
