allium nigrum -black onion (Zones 5–8).star-shaped flowers are white, but centers are dark black to dark green, often-washed-out appearance of white flowers, but the black centers of this allium are strong enough that striking 4- to 6-inch-diameter flowers bloom for several weeks, but even afterward, the seed heads look fine for a while with some of the chocolate-colored heucheras (Heuchera spp. and cvs., Zones 3–8) or any other dark-leaved plant for some subtle color echoing.
