If I told you the above plant featured tasty green vegetables, you'd probably think I was crazy. But as it turns out, the young shoots of Common Greenbrier (Smilax rotundifolia) are edible, new thorns and all. The key is to gather only the tender growing tips (see example below), snapping them off where they break cleanly. I usually eat them fresh off the vine, chomping on the thick end while the tendril tips dangle from of my mouth. Maybe I am a bit wacky after all.
