The Dahlia Plant!
I have grown Dahlias for several years, and in all that time I did not follow any of the specific dos and don'ts for planting them. I just did it my way (I have admitted, I'm no expert) and since they handled my fumbling and grew anyway, to me the dahlia is the perfect flower. The blooms come in all types and sizes. From a tiny 1" blossom to a gigantic 13" blossom (there may be bigger blossoms but I can only speak of what I have grown); ranging from 18" to upward to 6 feet tall; in so very many colors; in so many classifications. There is truly no other plant like it. For good info on the how-tos of Dahlia growing, check out the different nurseries on line that sell Dahlias; they have a wealth of information.
