That looks like a dandelion seed head on the left in the image below; however, it’s actually about the size of a tennis ball. I think that this plant is salsify (Tragopogon porrifolius) and, if so, the plant’s unopened bud on the right soon will become an interesting pink or purple flower.
Salsify is a wild root vegetable that’s native to Europe, but has become naturalized in North American fields. It’s also known as the oyster plant or vegetable oyster, reportedly due to its taste when cooked; but, many reportedly think that it tastes nothing like an oyster.
According to some of the claims that appear when you search online for information on salsify, eating this plant will stimulate hair growth, lower blood pressure, boost immune systems, improve digestive health, increase metabolism, and help bone density.
