Biscayne Prickly Ash

Biscayne prickly ash is tolerant of occasional salt breezes yet no salt water flooding. This large native shrub or small tree grows from Key Biscayne to Southern Palm Beach County within the coastal hammocks.

Biscayne prickly ash is very drought tolerant with dark green, shiny compound leaves and unisexual flowers. The shiny black seeds are born in clusters and are eaten by cardinals and other seed eating birds. The larva of the giant swallowtail butterfly feeds on the foliage.

Due to the prickles on this plant, it is recommended that this be planted away from where people walk. Incorporate into a butterfly garden by planting other plants around it to keep people away.

Mix with wild coffee, saw palmetto, firebush, marlberry, stoppers and other hammock species. A super planting for giant swallowtail butterfly larva includes wild lime, hercules club and Biscayne prickly ash.
