The plant has been growing for about two months. It is over 7 feet tall with small yellow flowers. Leaves are untoothed with a few lobes. Detail photo of leaf included.
Hi Jesse,
your plant is a wild lettuce, Lactuca canadensis, a rather common native. It looks like you have good fertile soil! They do normally grow tall, though.
Sincerely,
