The word Calla comes from the Greek term for beautiful. And with her flaring, trumpet-shaped face ― beautiful she is.
Katharine Hepburns' famous movie words were my introduction:“The calla lilies are in bloom again. Such a strange flower suitable to any occasion. ...” (Stage Door 1937). That line stays with me, reminds me of being very young with no idea of what a Calla lily was, but gee it was fun imitating that Hepburn sound.
