Apparently I have cool climate plants: apple, avocado, lavender those are germinated from seeds and blackberry, and fig from cuttings also living in a hot and humid climate. Definitely they can grow here, but can they be farmed? Of course not without expensive climate controls
Blackberry and it's variants like dewberry are very common in the south and do fine in the high heat and humidity. It's almost impossible to kill. I have 4 different varieties growing wild and in planters at my house.
I also have many apple trees and they do struggle - even the native varieties. I think that's mainly due to fungus, aphids, and the poor soil though.
No idea about avocado.
Are you talking about the southern US? How can there be native apple varieties? I thought they were all originally from around central Asia and a quick look on wikipedia confirms this
"Native" might have been an excessively strong term. I should've said there are varieties that are unique to the region even though their ancestors originally came from Asia.
Wait, avocado and lavender are supposed to be cool climate plants?
They grow like weeds around here. The tomatoes the article cites don't grow as well, but are still perfectly farmable.
Besides, people have been adapting species for other climates for millennia. I don't think it makes sense to talk about entire species that way.
