This is a plant often ignored by bushcrafters and one I rarely see mentioned in forums or books
A member of the mustard family, the leaves (and flowers) of this plant are edible although relatively bitter and even more so after it has flowered, so pick the leaves when young. They can be added to salads but like most wild greens have that metallic taste that a lot of palates can't handle.
It is an antiscorbutic, but be careful with consumption at the bitters in this plant can cause vomiting..
It is said to release it's scent late in the evening and thus the name vespers is used in relation to this.
In plant symbology it represents Deceit.
