Gosh - I didn't think of C. rapunculoides - have that too but, since I don't mow mine, it doesn't look quite the same. That should be blooming now as well. Mine was introduced by a well-meaning family member and is almost impossible to eradicate. It scoffs at any chemical intervention and has a large tuber-like system that has to be dug out and all fine roots sifted out of the soil.
