Answer: Burpee's 'Plum Blossom' Snapdragons have the potential to grow 4' tall and would be first on the list. Burpee's 'Topper Hybrid Mix' snaps can grow 3' tall. Give one or both a try to see how they fare in your garden. You can order online at http://www.burpee.com, or phone toll-free (800) 888-1447.
