this is a "Henryi" clematis, a gift from my son. this is the first time in three years that he has bloomed. And yes, that is the correct spelling.
My father's name was Henri, with an 'i," although most people used a 'y.' He hated it, never used it in life always preferring to go by his middle name. Strangely enough the name he used was not really his middle name, which I found out when I took care of his estate and had to find his birth certificate.
He was French-Canadian and as was the custom back in the day his parents gave their children several names. Henri was only one of five names he had. Three of which I never knew, but when strung together and spoken in French became very lyrical.
Not so much in English though! How appropriate that my son would find and gift me with a beautiful bloom that is spelled in such an original way...just like my daddy.
