Thank you Chris. I love Dynamo, it is one of the smaller semps and pack such a wallop of color. Summer seems to be it's most colorful time of year.
Here is what it looks like now, just starting into changing color.
The largest rosette is 2 1/2" across. I've had it for several years, so think this is the maximum for it. I don't fertilize, so it might get bigger?
It was one of Cynda's (Perennial Obsession) favorites when I got it. So glad she talked me into this one.
