Soils: Wet to moist, periodically inundated freshwater or brackish sandy, limestone, or organic soils, with or without humusy top layer.

Nutritional Requirements: Moderate; can grow in nutrient poor soils, but needs some organic content to thrive.

Salt Water Tolerance: Moderate; tolerates brackish water or occasional inundation by salt water.

Salt Wind Tolerance: Moderate; grows near salt water, but is protected from direct salt spray by other vegetation.
