A description of Sideroxylon tenax is provided in The Flora of North America.
Tough bully is native to North Carolina, South Carolina, Georgia, and Florida. In Florida, it is absent from the panhandle.
In the Coastal Plain, S. tenax has occurred in longleaf pine-Carya floridana-oak woods, longleaf pine-turkey oak-wiregrass sandhills, scrub oaks, hydric hammocks, sand dunes, coastal scrubs, scrub oak/cabbage palm communities, saw palmetto thickets, Pinus clausa scrubs, salt marsh edges, tidal marsh borders, and river floodplains. It has also occurred on roadside disturbed sand dunes. This species prefers moist to dry, well-drained sandy soil with a humusy top layer and has been found in sand, loamy sand, and calcareous loamy sand. and mostly grows in xeric habitats as it has adapted a dense coat of hair to slow down the water loss through transpiration.
Associated species include Ceratiola ericoides, Pinus clausa, Quercus chapmanii, Q. geminata, Q. myrtifolia, Garberia heterophylla, , Sabal etonia, Lyonia ferruginea, Vitis rotundifolia, Bumelia, Smilax, Selaginella arenicola, Rhynchospora megalocarpa, Ximenia americana, Juniperus silicicola, Myrica cerifera, Celtis, Xanthoxylum fagara, Persea littoralis, Ardisia escallonioides, Rapanea guianesis, Parthenocissus quinquefolia, Plumbago scandens, Bumelia, Forestiera and Sageretia minutiflora.
The berries are dark purple, spherical to egg shaped and about 10 mm across; they have a sweetish pulp that is eaten by large birds and mammals. Flowers are borne in groups of up to 40 flower. It has been observed flowering in March, May through October and in December. It fruits June through November.
This species disperses by being consumed by vertebrates (being assumed).
Sideroxylon tenax has been observed at the Archbold Biological Station to host various pollinator species. These include bees from the Apidae family such as Apis mellifera and Bombus impatiens, plasterer bees such as Colletes francesae (family Colletidae), sweat bees from the Halictidae family such as Augochlora pura, Augochlorella aurata, Augochloropsis metallica, A. sumptuosa and Lasioglossum nymphalis, wasps such as Leucospis robertsoni (family Leucospididae), spider wasps such as Episyron conterminus posterus (family Pompilidae), thread-waisted wasps from the Sphecidae family such as Bicyrtes quadrifasciata, Cerceris fumipennis, Ectemnius rufipes ais, Isodontia exornata, Oxybelus decorosum, Stictia carolina and Tachysphex apicalis, and wasps from the Vespidae family such as Monobia quadridens, Pachodynerus erynnis, Parancistrocerus fulvipes rufovestris and Stenodynerus histrionalis rufustus.
