This is one of those cases where there are three hostas with the same name. None are registered with The American Hosta Society. The first one to be registered would become the "official" hosta of that name and the others would have to be renamed.

The famous English hybridizer, Eric Smith, is credited with originating this hosta. It is a small size plant with green foliage that has a gold colored medial (center) variegation. It bears white flowers in the late summer and is similar to H. 'Lyme Regis'.

"Plant is a hybrid very similar to H. 'Kabitan' but has white flowers on very straight scapes."

Paul Aden of New York introduced a plant of this name in the 1970s. It was a small size, green plant with a gold colored marginal variegation. According to The Hostapedia by Mark Zilis (2009), "...may no longer exist."

Hosta Helper will call this plant 'Golden Isle' (Aden)

According to The Hostapedia by Mark Zilis (2009), "...a third plant with gold foliage and purple flowers also bore the name, but Peter Ruh (thankfully) renamed it 'Sunny Isle'."

Hosta Helper will call this plant 'Calico Cat' (Ruh)
