Answer: Asparagus fern (Asparagus densiflorus) is actually not a fern but rather a member of the lily family. It is a tough "survivor" as you now know. Aside from making chemical attempts on its life, the only way to get rid of it is to dig up the fleshy root nodules from which it so readily returns. In a severe case, this may mean lifting existing plants from the bed in the fall and spading through the entire bed to locate and remove the underground storage nodules. Then reset the desirable plants and remain diligent to search out and remove any asparagus fern "escapes" which may show up later.
