Disclaimer: Foraging can be fun, rewarding and provide health benefits. As a novice forager, I will be sharing my foraging experiences. However, in order to be safe, always consult with local foraging experts and guidebooks before beginning foraging. Children should learn to forage safely by being guided by experienced adults. Never ingest anything unless you are certain of the identification and safety of the plant. Some plant species are inedible and some are poisonous.

Field Pennycress (Thlaspi arvense)

Date Location Notes Images
June 3, 2012 Southeastern, New Hampshire The seed pods on Field Pennycress are many times bigger than the similar-shaped pods on Field Pepperweed (Lepidium campestre) and Virginia Pepperweed (Lepidium virginicum). After I keyed out this plant for identification, I was still left with several possible mustard genuses. I went through those possibilities to be sure that I had the correct ID. It would have been easier had I counted the number of seeds in the seed pods.
  • Fruit is a silicle (up to 3 times as long as wide).
  • Silicle not inflated.
  • Silicle compressed at right angles to the septum. (By the way, I can’s believe I even know what the words “silicle” and “septum” mean!)
  • Leaves not confined to the base of the plant.
  • Silicle with four seeds. I did not know this, so I had to key out the genus: Lepidium and Iberis to confirm that it did not have 2 seeds.
  • Flower petals all of similar size.
  • Silicle is oval.
