Dahlia 'Thomas A. Edison' is a heritage classic and still one of the deepest purple dahlias you can grow. Its large, fully double blooms come in a rich, velvety royal purple.
Tall, vigorous plants flower from midsummer until frost. The blooms make excellent cut flowers.
Plant the tubers in full sun after the risk of frost has passed. Lift and store them indoors over winter.
