I found a possible field pennycress in my lawn can you confirm if this is feild pennycress? Massachusetts usa
Answer
Dear Sorgenman, good morning. I can't see the details necessary to make a confident determination. As best I can tell, the plant you have photographed has a conspicuous basal rosette of leaves and few stem leaves. This would not fit with the morphology of Thlaspi arvense (field penny-cress). This plant looks similar to Arabidopsis thaliana (mouse-ear thale-cress), another non-native mustard that is introduced to New England. If this hypothesis is correct, you should be able to find branched hairs on the leaves of this plant. Best wishes.
