I got Barracuda Bay in 2015 and it is up to 9 fans now. I was impressed with the branching in 2018 and 2019. I've not seen rust on it. Even though the coloring does look muddy, I guess it is the teeth that make this one so interesting.
There are a few polys in the database, and I was able to capture one in 2018.
It has done okay in my garden and usually begins blooming at the beginning of July and into August a little. As long as it continues to look like this, I'll probably keep it.
