Appearance

''Smilax herbacea'' is a vine with alternate, simple leaves, on climbing stems. The flowers are green, borne in spring. The plant at first looks like asparagus when it first sprouts out of the ground. The plant can grow over 8 feet tall without support, but will eventually fall over unless it successfully finds external support. As flowers start to develop, at first they look similar to small broccoli florets on thin stems.
