Accent or specimen tree in residential and commerical landscapes.
Ecological Restoration Notes:
A rather uncommon element of mesic coastal hammocks, rarer inland.
Availability:
Grown by one or two native plant nurseries in South Florida.
Description:
Medium or large tree with a round-topped to cylindrical and dense crown from a few stout, thick branches. Trunk 1-3 feet in diameter, often leaning. Bark brown, thick, roughened by many furrows and ridges. Leaves dark green above, waxy beneath, 3-5 inches long, aromatic when crushed, often contorted by galls.
Dimensions:
Typically 20-40 feet in height in South Florida; to 77 feet in Florida. Sometimes as broad as tall or broader.
Growth Rate:
Moderate.
Range:
Southeastern United States west to Texas and south to Miami-Dade and Collier counties. Reported for the Monroe County Keys, but this perhaps represents a misidentification of P. palustris.
Habitats:
Primarily coastal hammocks but sometimes inland.
Soils:
Moist, well-drained sandy or limestone soils, with humusy top layer.
Nutritional Requirements:
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:
High; does not require any supplemental water once established.
Light Requirements:
Full sun to light shade.
Flower Color:
Whitish or greenish.
Flower Characteristics:
Inconspicuous.
Flowering Season:
Spring.
Fruit:
Dark blue to nearly black shiny drupe, 1/2" long. Late summer to fall.
Wildlife and Ecology:
Provides significant food and cover for wildlife. Larval host plant for palamedes swallowtail (Papilio palamedes) and spicebush swallowtail (Papilio troilus) butterflies.
Horticultural Notes:
Can be grown from de-pulped seed. Plant right away; seeds do not store well. Sprinkle soil over the seed to just cover. Place container in light shade or full sun.
Comments:
This handscome tree looks very similar to Virginia live oak (Quercus virginiana). Plants sold in the nursery trade as this species are often swamp bay (Persea palustris), a species that requires much wetter soils. The dried leaves can be used as a substitute for commercial bay leaves.
