This is one of those cases where there are two hostas with the same name. One is registered and, therefore, the "official" version of H. 'Cathy's Clown' while the other is a non-registered plant and needs to be renamed to avoid further confusion.

Chick Wasitis of Bridgewood Gardens in Maryland registered this cultivar of unidentified parentage in 2011. A medium size plant, it grows to 16 inches in height and a width of about 36 inches. The leaves are medium green with creamy white marginal variegation. They are moderately wavy, broadly ovate and have irregularly rippled with a moderate bloom on the bottom. It bears tubular shaped flowers from June into July.

Similar cultivars include H. 'Alley Oop'.

The hosta shown above was photographed in the Leaf Show of the 2010 National Convention of The American Hosta Society in Minneapolis, MN. It was labeled as H. 'Cathy's Clown'. According to Chick Wasitis, this was a tissue cultured cultivar which was once considered for that name but was found to be too unstable to be introduced by him. Subsequently, he introduced and registered a different plant as H. 'Cathy's Clown'. Some of these streaked plants have been sold by another source. Plants of this type need to be given a different name.
