This
tissue culture sport of H. 'Frances
Williams' was originated by
Marc Laviana of
Sunny Border Nurseries in Connecticut and registered by
Alex
Malloy of New York in 2001. It was granted a
U.S. plant patent in 2006.
The
medium size plant grows to around 17 inches in height with a
spread of around 36 inches. Its leaves are very broadly ovate,
heavily corrugated and have thick substance. The near white
flowers bloom from mid-June into July.
According to
The Hostapedia by Mark Zilis (2009), "The margins...are significantly wider than those of 'Frances
Williams'...it does exhibit some spring desiccation burn and
needs to be sited properly." (see below)
