Mary's Gold is a tet?!?! ATP and the seller I bought from list it as a dip! In addition to its great looks I bought it with the idea of crossing it with another dip. I am not happy about this!
Interesting to read that MG doesn't like the shade too much. It was a first-year plant for me but was one of only a couple first-years that didn't bloom for me. It is in more shade than the rest so I guess that explains it. I may have to move this one to a sunnier spot to make it (and me) happier!
