Catananche caerulea "Amor Blue" (Cupid's Dart)
Catananche, or Cupid's Dart, grows on slender stems above gray-green, grass-like foliage, and it's fine violet blue flowers are ideal for cutting. The buds are similar to strawflowers and may be startling, as they seem more like seed pods, but before you know what hit you, one of these lovely flowers with violet centers appears. Interesting to know: Catananche was once used by the Greeks as a love potion; its Latin name, "Katanangke," means "strong incentive."
