We recently bought some neighboring pastureland and are trying to improve it- it is in very poor condition, for many years it's just been cut and taken for hay- no regular mowing, no fertilizing, no liming, etc. It is unfortunately mostly foxtails, broomsedge, and weeds, with a little bit of fescue every now and then... (argh). Anyhow, these little weeds are all over the place and I'd love to know what they are. They form a rosette of leaves at the ground, maybe around 8" in diameter, leaves are long ovals and very hairy on both sides. Sends up a single spike (also hairy) with several buds at the end- buds seem to have very dark stripes closely spaced before blooming- from a distance they look black. Flowers are yellow and petals are thin (almost string-like?), and sort of resemble the tiny wild daisies I see some times. I have searched and searched and can't seem to find a match. I'm including pictures, and I apologize as my phone doesn't take good close up pictures, always wants to focus on the background! Thanks in advance for any information you can offer!
