Pauline Banyai of Michigan registered this cultivar of unidentified parentage in 1986. It is a medium size plant with chartreuse to gold colored foliage that is heavily corrugated. The white flowers bloom from mid-July into August.

According to The Hostapedia by Mark Zilis (2009), "...Russ O'Harra had introduced, but did not register, another 'Gold Coast'. That plant became 'Claire de Lune'."
