Sam, The deers here chomp on my Dahlia readily. They do not seem to like tree dahlias, but it could just be that they're not hungry enough. Alberto said it. These plants are tender. I like them quite a bit and tried growing them when I lived in Louisiana. It never worked out. The leaves always seem to melt under summer heat, even in the shade. Often it is so hot and wet that the tubers are cooked underground. The conditions most likely allowed pathogenic organisms to do their things as well. I only managed to flower a single hybrid which started growing in late winter and flowered in early summer.
