Dinnerplate dahlias are SO fun to grow. They are difficult to work into arrangements but look stunning alone in a vase. They take longer to bloom and have less blooms per plant but I think they are very worth the time and space in the garden. I absolutely love this color palette of creamy peaches, magentas and reds.

Your second sentence answered my questions about the Dahlia I am growing. Thanks. They are definitely gorgeous.
