Yesterday afternoon I spotted a few emerging wild asparagus shoots while walking through an olive grove. Wild asparagus is classified as Asparagus prostratus and thought to be a separate species then (rather then a subspecies of) the commercial / cultivated A. officinalis.
I snapped off a few stems and kept looking, finding more, but also came across a very similar plant, growing in the same habitat with slightly longer, less rigid stems.
See comparison of photos below. The first is wild asparagus. The second photo is of a plant that grows in the same habitat and looks very similar, popping up as a shoot in early spring and snapping off at the tip.

Below is the yet-unidentified asparagus look-alike. I will try to take some more photos of the developed plant / leaves for reference. From what I observed I believe it grows into a spiny vine with leaves that look like a Smilax spp. with a spiny underside. I will verify. Please let me know via the comment forum if you have any idea what it might be.
