KallistaThis hybrid between R. lindleyi and R. nuttallii was created and named by Felice Blake Kallista, Victoria, Australia. It is a unique cultivar as it has larger flowers, with more bell shaped blossoms to the truss as many as 10 and sometimes 14! The flowers are white with a yellow throat and HUGE! Each blossom can measure 6" long and 6" in diameter. I remember seeing a photo of several plant hunters standing around drinking wine out of these flowers.
