Hi,
I see that you have posted pictures of both. I am trying to validate existing name tags and identify plants where the name tags have been lost. I have an inventory that says that I have both of the above and have two in that flower bed that are blooming and have a slightly different shade of yellow. One's blooms are lighter colored and seems slightly larger than the other. Your pictures are great but I can't differentiate between the two on that basis. Could you possibly provide some comparative descriptions to help out?
Thanks,
Bobby
