Availability: In Stock

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.

Gorgeous color

5 out of 5 stars Jul 12, 2020
I had Sweet William blooming everywhere and this color was so rich and beautiful, in contrast to all the other colors - pinks, white, red, multicolored - I've saved seeds and hope I can keep them blooming every year. I can't think of another flower that puts on such a profuse display - there were large clusters everywhere.
