This little iris was hybridized by Harald Mathes of Germany, who does much
interspecies work. In my estimation, he is the current "dean" of
interspecies bearded iris hybridizing. The parentage of Gladbeck Yellow is
((Little Dolly x I. aphylla) X (I. reichenbachii x I. aphylla)) and is supposed
to be TET. It looks like a yellow aphylla.
