I can't offer any info on the inheritibility/genetic stability of green petals, but in one population of T. decipiens in the Florida panhandle different petal color forms abound, including what I consider green (not yellow bordering on green). I have watched some distinctive plants, and they return the same color each year. Here are some examples, all from the same locality:
Green tinged with maroon:
Yellow plant and typical maroon plant together:
Something is unusual about this particular site having a wide range of color forms mixed together, as a few other FL populations 20 or so miles away have nothing but typical maroon colored petals amongst hundreds of plants with no variation.
