No pic but it is "real"... and this is how it came about:
Originally named 'Karen', renamed because of the Bob Olson's 'Karen'.
Giant, blue-green leaves with heavy substance.
Named for Carolyn Harstad's daughter, Karen. Carolyn changed the name from H.'Karen' to H. 'Karen Deborah', 3/03 .
And here is the one for Karen: (this is Bob Olsen's Karen)
