I suggest you try Native Seed. All southwest Desert adapted varieties of whatever.Working on assembling a master list of extreme heat/drought tolerant veggies and fruit tree varieties. Intense heat, warm arid desert, borderline desert technically because we get 14 inches of rain each year and not less than 10. I’m taking variety suggestions if anyone wants to @ me, I’d be grateful.
Don’t order fruit trees online, everyone ships far too late for desert climates. Visit a local shop and buy there, the earlier you buy the better.
If a package says an item can take full sun, that doesn’t mean desert sun so a lot of stuff benefits from 50% shade in the latter half of the day.
Good luck!
