Question
Using the simple key I got to Barbarea vulgaris (yellow flowers, deeply lobed alternate leaves, and the ridged stem matches). Common in sunny places next to a trail (service road) in Great Meadows National Wildlife Refuge, Massachusetts.
Answer
Dear jfc, Yes, the plant you photographed looks like Barbarea vulgaris (garden yellow-rocket). This is a non-native member of the Brassicaceae that flowers early in the season. It has edible leaves and flowers, and while extremely nutritious (as evidenced by testing), the leaves are bitter for most palates. Best wishes.
