common groundsel, Senecio vulgaris
It's fall. Pretty soon there won't be any wildflowers blooming? Or maybe we will just have to watch for groundsel. I've seen it blooming in January, in sheltered spots away from the coldest effects of winter. Sure, it's an Eurasian plant that we don't much celebrate, and one we've gone to some lengths to control. But it's something. Those lengths include introducing cinnabar moths to eat it. Wiki says their caterpillars get excited when they take a bite. What does an excited caterpillar look like? Common groundsel grows in every state and country, and in GL and on SPM. Beyond us there may be nowhere it does not grow. Lenawee Co MI, 3/29/12. Aster family, Asteraceae.
