The seedpods are small, round and slightly notched at the top. The seeds have a spicy/peppery taste similar to radishes. I usually just bite the seed-stalks off the plant. The young leaves also have the horse-radishy taste but by the time the seeds appear the leaves have become to power-tasting for most people to eat. The young, tender seedpods also add a bit of a kick to salads.
These plants seem to thrive in waste areas. I see them growing along all the major roads and freeways in Houston. They even grow out of the cracks in the concrete barriers at the toll road toll booths starting in late winter (February) into early summer (May-June). Their shape is distinctive, look for a single stalk that branches out into multiple, "bumpy" stalks.
