IMO, I think most flat peaches are harder to grow than regular peaches.
As Alan mentions, they all cling really hard to the shoot and have more than their fair share of pick damage as a result.
Without looking it up, I think I’ve been harvesting some of the NJ flat peaches for at least 3 years.
TangOs is a great peach but is badly affected by rain. The fruit gets very ugly/spotty with very much rain.
BuenOs isn’t affected by rain, but is a very sub-acid yellow peach with really very little flavor. A lot of sugar, but not much peach flavor. I have one BuenOs tree in my backyard and three of those trees at the farm. Strangely, all three of those trees at the farm died this year. These were the only peach trees which died at the farm this year, except for a white peach. They collapsed from canker. It’s weird that these were about the only trees that died, but really no big loss, since I don’t like the flavor.
BuenOs II is the more traditional yellow flat peach (with some acid). This is the first year I’ve harvested anything off these trees, but the fruit is VERY spotty from the rain. It’s the result of bac. spot, not scab. Better flavor than BuenOs, but still nothing special about the flavor of this peach.
TangOs II is the flat green white peach. This is the first year I’ve harvested it. Strangely, it’s supposed to be the hardest one to grow of the flat peaches. It is spotty, to be sure, this rainy year, but not near as spotty as BuenOs II. About as spotty as TangOs. I’ve not tasted this peach yet since its not ripe yet.
The clear winner of flat peaches so far this year is what is labeled as Saturn, but what I’m pretty sure is Galaxy. Foliage is fairly clean in this very rainy year and the fruit is blemish free. Very sweet fruit, but with the traditional lack of peach flavor common for white peaches imo. Still lots of customers loved this fruit. I just don’t like very many white peaches, but many people do. For selling fruit, this is a cultivar which is one of the easiest to sell. It’s easy to give a samples of this peach and people want the peach after tasting it. I hope to make some copies of this tree this fall.
Flat Wonderful is a NJ release recommended for home orchards which is licensed for the Gurney’s/Henry Fields conglomerate. I’ve grown this one for quite a few years. It hasn’t been very productive in the past, but this year it was loaded. It doesn’t taste as good as TangOs, but is more unique in flavor than BuenOs and BuenOs II. They are a smaller peach and so make nice samples to hand out.
Sweet Cap hasn’t ripened yet but is spotty, as is Sweet bagel. I’ve no idea how these taste, but they don’t look very pretty this year.
