Like most of you, I do good to get them to last 2 years in my garden. I think the longest lasting for me are the Tokajer. Mine are on year 3 and looking good. They do come true from seed and are a nice mellow orange. I loved the yellow ball ones I grew a couple years ago, but they did not reseed. I think my other one now is a reseeded Arizonia, which looks like the normal orange'yellow. I will be glad to save some Tokajer seeds this fall if anyone wants some. They were taken out of occupied Germany.
