I got this plant for $2 in a close-out sale some 7-8 years ago. It was a single growth and only about 2" LS, so it took a while to grow back.
Traditionally it was known as Paph Leyburnense 'Magnificum'. However, the RHS now recognizes a previous registration, so it is supposed to be named Mrs. Haywood.
It is a surprisingly simple hybrid: (charlesworthii x [druryii x superbiens])
