Walters Gardens, Inc. of Michigan, of Michigan registered
this tissue culture sport of H. 'Heartsong' in 1997. It is a medium size plant
with pale lavender flowers in July.
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."
