European heliotrope
The scientific name of european heliotrope (*Heliotropium europaeum*) has an interesting backstory. In Greek myth, Clytis was madly in love with Helios, the sun god, but this was unrequited, and Clytis became inconsolable. She stopped eating, and Helios, feeling sorry for her, turned her into a flower. This doomed her to follow the sun for all eternity. The tale lives on in the name european heliotrope, which comes from "helio" (meaning "sun") and "trope" (meaning "to turn").
