I am looking for information on what plants are heliotropic, and among these whether the leaves or the flowers are heliotropic. I am particularly interested in the latter kind.

Of the latter, so far I have found arctic poppies, sunflowers (in bud form), and buttercups. It looks like at least some lupins follow the sun also, although I'm not sure if it's the flower or the leaves that do this. (Heliotropes themselves have leaves that follow, but the flowers do not, if I understand correctly.)

Any suggestions on other species whose flowers or leaves demonstrate heliotropism would be appreciated. Thanks!

Google is a good source of info, you just have to spend time wading through websites. Here's one with some movies that says legumes and malvas have heliotropism. I don't know which legumes in particular, it might be a good experiment to try a few pea and bean seedlings and see if they will track the sun.

Here is a link that might be useful: heliotropism

Here is a link to the USDA listing of heliotrope plants and you can click on each plant listed for further details. Gives distributions, growing conditions, etc.
