Grown by the grandparents (they called them Golden Glows). Mildew can be a problem, and they can get leggy and need support. But a consistent bloomer over the years.

Many years ago I would see this plant growing along fences in Colby, KS and fell in love with the beautiful yellow blossoms. My aunt told me they were called "Golden Glow" and gave me starts from her yard. Golden Glow is a very old "heirloom" plant, that apparently grew out of favor for many years. I plant it wherever I happen to be living and have given starts to friends. When I lived in Northwest Kansas, I did have to tie the plants to the fence because it was always windy, but I live in Northeast Kansas now and have not had to do any tying. A nursery owner told me once that people only plant "Golden Glow" in their yards when they want to hide something. I told her I grow "Golden Glow" because I think it is beautiful and I love the flowers. The flowers last well as cut flowers, too!

Very tall, very pretty, very hardy, prolific without being aggressive. Very easy to transplant and seems to grow equally well in sun or part shade. Only problem I have, since I live in a very windy area, is that they sometimes need tying up.

A very tall perennial (6-8 feet) for the back of a sunny border. It blooms throughout September in Newfoundland. Full sun and well-drained soil are ideal. It can be used as a good cut-flower.
