I would like to plant a white wisteria and am looking for the most fragrant one (or at least a very fragrant one). I have a book on wisteria which says "Jako" is the most fragrant white. One nursery told me "Snow Showers (also known as "Shiro Noda") is the most fragrant, but the book said faint scent. Several nurseries have "Texas White" but it is not in my book and I don't know how it compares. Any help would be appreciated!
