  • Photo of Smilax herbacea (Smilax herbaceas)

Phonetic Spelling:SMIL-aks her-bay-SEE-uh

Genus:Smilax

Species:herbacea

Family:Smilacaceae

The Carrion Flower emits a strong scent, often likened to that of decaying flesh or dead rodents. This plant typically thrives in damp forests, dense thickets, and along wooded banks, showing adaptability to various soil types, though it favors moist conditions. The Smooth Carrion Flower stands out among the Smilax species due to its lack of thorns and the absence of hairs on the underside of its leaves. It features an elongated stem that supports clusters of berries along the vine. Notably, Smilax plants are dioecious, meaning that male and female flowers grow on separate individuals, preventing self-fertilization.

Regarding fire safety, this plant is highly flammable and should not be cultivated within the defensible space around your home. It is advisable to choose plants with low flammability ratings for areas closest to your residence.
