Gracing gardens for centuries, Black Knight scabiosa's nearly black, deep crimson, 2 in. pincushion-shaped flowers have dramatically contrasting white stamens. From summer until frost, above lacy-leafed mounds, wiry 24-36 in. flower stems wave in the breeze and are plenty long for cut flowers. Butterflies, bumblebees, and other pollinators adore Black Knight scabiosa. Usually grown as summer annuals, plants are perennial in zone 10. If some spent flowers are kept on plants, Black Knight will usually self-sow.
