It started growing in one of my Mother-In-Laws potted plant. Seeds probably dropped by a bird. Can you identify? Nancy
Looks like a "cat's ear" or "false dandelion" (Hypochaeris radicata). If it is then the seed would not have dropped from a bird but drifted through the air like a dandelion's.
Hypochoeris 'seeds' would be more like dandelion, with feathery pappus at the end of a long narrow beak. These look more like a Bidens, with a few (barbed?) prongs coming directly off the achene. Possibly B. pilosa or a relative?
