That surely is one wonderful calla lilie, is it a huge type of the small compact ones. For some reasons the small compact ones in my garden die really quick... and they are the most expesive!! I have the classic giant white ones. White spead out quiet good. I'll have to show you a pic of them. Well anyways back to this one picture of yours. SO you said the flower lasted for months.. In a glass of water? or on the plant, something worth hearing about, hope to hear from you soon. Thanks
