Impossible Question to Answer

Pomegranate takes well from cuttings and are perhaps one of the more resilient for field growing, much like Trident Maple. They will fatten up quickly in the ground provided they get enough water and nutrients. If you decide to plant some, I'll hit you up in 10 years for a tree.

I'm in zone 7.

I've wanted to play with the American snowbell for a while, but it seems less cold hardy than the Asian species and I've never found anyone selling it. Halesia caroliniana looks really cool and would be fun

I've seen a couple of people growing various Aronia, especially Aronia melanocarpa 'Brilliantissima'. Not sure how well it propogates, but it has wonderful fall color, nice winter berries and low disease pressure

Gary Clark was really enthusiastic about chalk maples (Acer leucoderme), and his collected ones at the winter silhouette show had a lot of potential. Super tiny internodes and Gary said their vigor is similar to tridents

There's got to be a deciduous oak species that'll work for bonsai, though I don't have any ideas on which ones to try

I haven't heard of chalk maples. I'll look into them.

As for deciduous oaks, Quercus phellos seems to be a good option. I also have some Quercus lobata x macrocarpa that I'm testing out. The leaves look like valley oak, and it's cold hardy.

Pomegranate Production

Pomegranates have been grown as a common backyard crop for decades in the South. In recent years, there has been an increased interest in the commercial production of the fruit in Georgia and surrounding regions. This production increase is largely in response to increased demand for the fruit...

There are varieties hardy enough to grow in Zone 7, possibly Zone 6 with sufficient cold protection. Russian Pom comes to mind.

Hardy to 7°F, and it prefers temperatures above 85°F for more than 120 days per year.
