"Asuka", a deep magenta Japanese Morning Glory, with blooms reaching a diameter of 5-6 inches across. This is one that was begining to bloom last year before the Armadillos succeded in digging it up. I got no seed from the vine and have replanted the few seed I had left this year and will hopefully have photos to add in due time.
