Hedge mustard (Sisymbrium officinale)
This one has big enough leaves to make it a prime player in the salad bowl. Note the slender seed pods that hug the stem. There are lots of wild mustards around. Perhaps you have a different one.

Wall flower (Cheiranthus kewensis)
I suspect this blew in from someone’s garden as it is not listed as a wildflower in any of my books. It is too pretty to eat, but I am working up the courage to taste it. Those mustards can have surprising tastes: hot, spicy, bitter, or all together!

Peppergrass (Lepidium virginicum)
The seed pods of this prolific plant are known here at my farm as Poor Witch’s Peppergrass. They are sweetly spicy and make a much better seasoning than the peppers we are used to using. It is non-inflammatory too.

Cow cress (Lepidium campestre)
The mustard family continues to pop up everywhere with lots of treats for our tongues. The seed pods of this one are spicy and yummy, but the leaves are a bit too tough for my salads.
