Thanks to all who have commented. LOL I have noted the various Spelling in the name. Some say Mari's, others say Marry. (I have not gone to the Kew to check it as yet) I however did go on the Internet a while ago to have a look because I have 2 Plants. One bought labeled Mari's Song and the other Marry Song. The flowers are a bit different. One has more yellow than the other. Any comment that would clear this up?
