Lucy Grand does not appear to have any registered crossings using it as a parent even though this plant was registered in 1956. It is heavily influenced by Cym hookerianum species which represents 40%. Cym tracyanum is also represented by 25%. This explains its open shape, perfume and spots. It is mated with a standard green pure colour. Progeny outcome will be an open shape, standard flowers with perhaps perfume and some spotting. Mid to late season blooming.
