I'm wondering if anyone has looked into growing Cherimoya. From my understanding, though it is from a tropical area, it grows best in high altitudes because it is colder there. Would this fruit work in our climate around Portland?
I found this interesting, from a sister organization in CA:
https://www.crfg.org/pubs/ff/c.....imoya.html
It reads as though it’s not cold hardy enough for the PNW, and was/ is recommended for specific regions of CA. It also sounds too vigorous for a greenhouse, with up to 8 feet of new growth per season!
Found this an interesting quote, “Mark Twain called the cherimoya "the most delicious fruit known to men.” The fruit appear quite large, too, which often indicates a long warm growing season… First I’ve heard of it, though 
Yes, the Pawpaw is very sweet, also - at least the variety i tasted at the 'All About Fruit Show', and it reminded me of the taste of Cherimoya.
This spring I planted a pawpaw seedling, and a second small one, here on the central Oregon coast: I'm not sure it will get enough heat and sun, though. Does anyone have any thoughts on how it will do here? There is some light freeze in winter, but generally wet and mild, with summer upper 60s, breezy.
Many of us are growing pawpaws in the Valley. Growing pawpaws on the Coast is a bold proposition. I met a lady who grew lots of fruit up close to Mt. Hood that I didn't think would ripen. Also, we are getting a ton more heat units than we ever got before, so it may work. I would love to hear how that works out.
