This sport of H. 'Tambourine' was registered by Ron Snyder of Minnesota in 1999. It is a medium size hosta with greenish yellow leaves that have a white marginal variegation. The foliage is moderately wavy, ovate and slightly shiny on the bottom. Medium lavender flowers bloom in July.

According to The Hostapedia by Mark Zilis (2009), "...I realized that 'Harmonica' was not the gold-centered version of 'Tambourine'. Instead, it matches 'Sea Dream' in almost every mound, leaf, and flowering characteristic."
