admmad,
Thanks very much for that response with all that great information! This has lead me to believe that as a gardener, I really have no need to distinguish between the two. If the only difference a trained eye can detect between the two plants foliage is a little blue tint, and if you don't get reliable consistent differences in the blooms, to me there is just no point on trying to guess. Now that I know more, what I at first thought was an incorrect and irresponsible representation by sellers of calling the plants 'fulva Kwanso Flore Pleno' I now consider to probably be the best policy.
Looking at my plants, some with very different foliage, bloom coloration, and shape, it appears to me that there must be several very similar daylilies available also, so I guess mine will display that very impressive name often seen on many of my other garden plants, NOID!
