Tropical Fruit Discussion / Zanthoxylum

Something I found interesting, as both are deciduous.
Zanthoxylum americanum
Americanum has already dropped all leaves. It started turning colors even before the weather cooled, but after one mild freeze it dropped. What leaves are in the photo are actually a sweet potato vine that tends to climb up it.
Zanthoxylum simulans
Simulans is still green and shows no signs of turning.
For context, my nightshades have died, marigolds are half gone or just hanging on, and my fig is dropping its leaves. My poncirus and Thomasville still have leaves, although the Flying Dragon elsewhere in the neighborhood is mostly bare. I suspect americanum is sunlight-mediated. I'm unsure what simulans responds to.
This may be the difference between a plant whose range is zones 4-7 (americanum) versus 6-9 (simulans).
