This is the only yellow blooming cultivar that I know about. I see it infrequently here and there. Most arboretums and botanical gardens have some. I have seen some sold at some nurseries where I worked in the past. I remember nurseries in the Chicago and Philadelphia areas that always sold Trumpet Honeysuckles and other woody vines in a certain section of the sales yard, and there were always more red or orange-red selections sold than yellow. This yellow cultivar is known to have early defoliation from leaf spot disease some years of really humid summers, which happens more down in the Southeastern US than in the North. Otherwise, it is considered as a wonderful woody ornamental vine (liana) that I think is really cool also.
