Misc.: The young shoots are edible and are considered by some to be the most flavorful of the Smilax. Stone, in 1910, says "This is the commonest and stoutest of the Greenbriers. While apparently not common in the Pine Barrens proper, it makes the thickets along the edge of the coast strip almost impenetrable with its strong woody stems and stout thorns" (352)
