Silphium compositum from Chase in SC

Posted on |

Howdy! I found this plant growing on a sandy slope in Clarendon county during the third week of September. Any help is greatly appreciated. Thanks!

Hi Chase,

your plant is called Silphium compositum, the Kidneyleaf rosinweed.  I prefer the scientific name! It is related to the sunflowers and has small yellow flowers much like those. The leaves can be quite variable in shape, but are mostly at the base of the flower stalk.
