Dark maroon flowers against purple-tinged leaves will draw you in to touch and admire. 'Black Adder' is a quick to bloom variety, blooming its first year when sown indoors. Low maintenance and beautiful in rock gardens and containers, too! In the kitchen, the mild-clove-flavored petals make a colorful garnish to salads, desserts, and cold drinks. (The flower's central disk, while edible, can be bitter.). Resow every year so you'll be sure to always have flowering plants.
