Delphinium Black Knight


Delphinium Black Knight Delphinium Cultorum is a hardy perennial that is one of the most known classic garden flowers. Black Knight Delphinium features mounding, deep-green foliage with deeply-cut leaves and produces gorgeous spikes of large dark-blue, violet flowers with a black center. Blooming all summer Delphinium can re-bloom in fall if the flower stalks are removed right after flowering. The hummingbirds are attracted to Delphinium flowers.
