@edweather, yes, we got some good peaches/nectarines from from the local market and I started about 10 from seed. 3 made it and out them only one is doing really well. You can see in my thread here: Starting Peach/Nectarines from pits - #35 by jeremymillrood .At this point I can’t recall if it was even a good peach or not, and even if it was that doesn’t necessarily mean this tree will produce good fruit, but I wanted to see if I could do it…
As far as those other peaches go, they were specifically recommended to me by JF&E as being ones that are the best tasting.
