I had no idea what carrot flowers look like. I never even thought about.

Apiaceaeセリ科  Daucus ニンジン属
Common names: wild carrot, bird’s nest, bishop’s lace, and Queen Anne’s lace

D. carota was introduced and naturalised in North America, where it is often known as “Queen Anne’s lace”. Both Anne, Queen of Great Britain, and her great grandmother Anne of Denmark are taken to be the Queen Anne for which the plant is named. It is so called because the flower resembles lace; the red flower in the center is thought to represent a blood droplet where Queen Anne pricked herself with a needle when she was making the lace. The function of the tiny red flower, coloured by anthocyanin, is to attract insects.
