Flower Friday: Burr marigold

Burr marigold is an annual wildflower that grows en masse in wetlands and along river and marsh edges throughout Florida. Its bright yellow flowers appear in late fall through early winter and attract many bees and butterflies. Its seeds have two barb-like bristles on the end that stick to clothing, hair and animal fur.
