Walters Gardens, Inc., Inc. registered
this sport of H. 'Heartsong' in 1997. It is a medium sized plant
with pale lavender flowers in July.
According to
The Hostapedia by Mark Zilis
(2009), "...the few clumps that still
exist in gardens have matured into nothing more than 'Heartsong'.
In short, 'Cupid's Dart' represents a temporary, juvenile phase,
probably induced by
tissue culture growth regulators."
