Moist, well-drained limestone or sandy soils, with or without humusy top layer.

Moderate; can grow in nutrient poor soils, but needs some organic content to thrive.
Salt Water Tolerance:
Low; does not tolerate long-term flooding by salt or brackish water.
Salt Wind Tolerance:
Moderate; grows near salt water, but is protected from direct salt spray by other vegetation.
Drought Tolerance:

Comments:
It is related to commercial cotton, and the USDA attempted to wipe this plant out in Florida in the early 1900s due to the fact that it is a potential host to the boll weevil. It is now illegal to grow wild cotton in Florida for this reason. It is also listed as endangered by the state of Florida.
