Hi Stan,
I'm pretty sure Park Princess is amoungst the smaller (BB) dahlias. They grow approx. 2' tall and very pretty! Be sure to post pics later in the summer when they're in bloom! :)

Pink Princess is a BB semi-cactus pink. It was originated in 1978 so it's an oldie- quite pretty, too if I remember back to when the husband allowed small dahlias in the gardens! I think it might be lacinated but that might be Park Princess- my brain is failing me - it's late!
