As for the air plants hanging among them, that’s an iffier deal.
The farther you work counter clockwise around the Gulf Coast, and in particularly Texas, cypress swamps become notably devoid of bromeliads because of the deeper and more regular invasions of arctic air.
But it’s not just our cypress trees locale so far south …
That makes that makes them such ideal air plant hosts.

Equally important is the reliability of them being flooded all winter long.
That water may be cold to the touch but also (ever so slightly) warms the air above where the air plants reside.
Out in the swamp we call that a microclimate.
Tropical air plants depend on it to survive.
