Smilax bona-nox, also known as saw greenbrier, is a flowering vine that is prickly with a one-seeded fruit.

[2][3][4][5] Smilax bona-nox produces fruits, one seeded drupes, that are dispersed by animals.

[4] Bullbriar, Catbriar, Dunes Saw Greenbrier, Greenbriar, Streychberry Vine, and Tramp's Trouble are common names for Smilax bona-nox.

It is distributed as far south as southern Florida, west to the edge of Texas and eastern Mexico, north to Maryland, Kentucky and southern parts of Indiana and Illinois, Missouri and Southeastern Kansas.

Mainly small animals and songbirds partake in their fruits but they are also eaten by deer and black bears.

[7] Smilax bona-nox is easy to grow by seed, and should be grown near lattice work or near something it can climb.

[10] Many animals use the fruit of Smilax bona-nox as food, including wood ducks, ruffed grouse, wild turkey, fish crows, black bears, opossums, raccoons, squirrels, and multiple species of songbirds.

[4] The Smilax bona-nox is tolerant to the occasional control burns and natural fires.
