I have two SVO 9951, Cl. thylaciochila 'Wide Petals' x Cl. russelliana 'SVO'. I ordered one; I received another as substitution for a plant out of stock. I hope I can flower them.
Fred Clarke writes both species have "an amazing fragrance!" He writes of the hybrid "The fragrance will be delicious and the flowers will perfume your whole growing area."
