Field pennycress-Thlaspi arvense-(cabbage family)is also known as stink weed(ya it does stink),fan weed,and french weed.The weed is considered either a winter or summer annuals that can grow up to .9m(3′) in fertile soil but most likely less than .6m(2′).The leaves are toothed with pointed leaves and the small white flowers are in clusters.The flowers can produce 20,000 seeds per plant. Stink weed is native to Eurasia-found in all of the U.S. and with distribution on 5 continents!You can find pennycress in the usual weed haunts:disturbed areas-one of my faves-pastures,croplands.Field pennycress may be common but as with a lot of weeds it has benefits to humans.According to ediblewildfood,com the leaves can be eaten raw or cooked and is suggested to get them before they flower.As always make sure you know what you are doing here.In addition to food, the weed is being grown for bio diesel as a sub for regular diesel(bio diesel is commomly made from used cooking grease).One more-bees love the nectar for the ones that are not endangered.

One sees this plant-weed for some and wildflower for others-all over my neck of the woods.Yellow Rocket-Barbarea vulgaris-a member of the Mustard family is a biennial plant that for the first year forms a rosette of leaves(germinates in the summer/fall) and in the second year shoots up a flower stalk that gets 1-2.5 ft. tall.The bright yellow flower has four petals with smooth leaves.As usual it is holding down some part of the planet-cultivated fields,roadsides,and waste places(my fave).YR is foraged as a food stuff being eaten as a salad-picked when young is best-and is a good source of vit c.The plant is a native to N.A. and Eurasia and is found in most of the U.S. and Canada.Like many weeds yellow rocket had a function in it’s previous life.In Medieval times it was used as a poultice for wounds.
