    The foliage of this cultivar begins as very bright yellow in spring and eventually turns just bright green during the heat of summer. It often in summer has some yellow branch tips. It is podless; therefore, a plant with all male flowers. It is sold by a good number of conventional nurseries and mail order nurseries. Oftentimes, when I see a plant with yellow or yellowish foliage, I first think it must have micronutrient deficiency showing up as chlorosis, especially iron chlorosis the most, which is a lack of green chlorophyll in the leaves. In this case, it is caused by a much higher level of natural yellow pigments hiding the green chlorophyll.

    New leaves come out bright yellow and it stays that bright yellow throughout its spring/summer life. Fall foliage, however, is quite blah. Just turns brown. Mine does not seem to produce seed pods, so that's good.
