A cross of R. burmanicum x R. nuttallii by Howard Kerrigan was most likely an attempt to create a R. nuttallii hybrid with more hardiness. We are not sure it is hardier than the species, but it most likely is a bit. The flowers are large, white trumpets with a yellow throat. The leaves are smaller than the typical R. nuttallii plant, but are very dark-green and textured. The flowers have won 'Best of Show' in some ARS chapters in the past. They are more flat faced and very ruffled.
