Large, purple-blue flowers make eye-catching bouquets and fresh floral arrangements. Karma dahlias were developed for the cut-flower market in Holland and are known for their extraordinarily strong stems and almost iridescent colors. Karma Dahlia Lagoon's fully double flowers measure up to 5 1/2" across and the color is phenomenal. Growing 32" tall, the plants produce plenty of blooms in midsummer and keep flowering until the first fall frost.
