There is NO yellow form of I. stolonifera. What you have pictured is obviously Turkish Topaz, which was erroneously sold as "I. stolonifera yellow" for years.
Sorry, Elm -- but this time I must disagree.
I grew TURKISH TOPAZ alongside Bushey's selection of the yellow I. stolonifera for many years. While "head shots" of the flowers are virtually indistinguishable, growth characteristics and fertility show that the two are distinctly different cultivars.
But you are certainly right about TURKISH TOPAZ being distributed as "I. stolonifera yellow" -- that's why I think it is so important that the true stolonifera be preserved.
