Hey @elivings1, I think some more context is going to be able to help steer you in the right direction. I believe you’re in Colorado, like myself and a few others. Is there a reason you want a container peach vs in ground?
I have a Pix Zee miniature peach in a container, mainly because it think the genetic dwarfs look cool and are manageable when to comes to frost protection. While the taste might not be as good as the non-genetic dwarfs, I was extremely thankful to have any peaches this year from my Pix Zee in that I was able to move it into the garage during our spring frosts - it tasted great to me. IMO, the best tasting fruit for our climate are the ones that produce regularly. I even ordered a few of the new Zaiger dwarfs from Bay Laurel last Fall.
I would check out the thread mamuang posted above. If you’re looking for the best tasting or highest yielding peaches then the genetic dwarfs are not going to be the best option. But if you’re looking for, IMO, a cool little container tree that you can protect and actually get peaches from each year, I’d recommend trying some out.
