I had Tuscawilla Tigress for about six years and even though I really liked it, I've been in downsize mode for a few years, so got rid of it. It multiplied well and was a bright spot in the garden.
7/5/2019 - clump shot. Blooms mid-June to mid-July in my zone 6b garden. Have not seen rust, but that is usually not a problem here.
7/3/2019 - guessing 3 to 4-way branching and about 15 buds based on this picture.
I do like those light midribs on it. It is an all-around nice plant.
