Unfamiliar Noxious Plant
This year, beginning in mid April, a small, prickly plant began growing in large numbers on our farm. We don't recall seeing these before. They have stems about 2 inches long, sparse, coral like leaves, and an oval shaped head with spikes, about 3/4 inch in length, that are soft when green, but become sharp when dry, They pierce the skin like the "Goat Head" seeds of the puncture vine plant, Can you help identify them from the included photo's. Thank you. Robert Mossbrucker
these plants are Bur buttercup. They grow very early in the spring and then flower and start setting seed heads and that is when we most notice them. I would use a 2,4-D product (broadleaf weed killer) on them. At this point you hope that maybe the herbicide will affect the viability of the seed forming on the plant.
