heliotrope
The origin and history of heliotrope.
Etymology
Heliotrope entered English from French héliotrope, which came from Latin hēliotropium, itself from Ancient Greek hēlĭotrópĭon. That Greek word is built from hḗlĭos, meaning the sun, and trópos, meaning a turn, so the plant was originally named for the way it turns to follow the sun.
