Senecio Linnaeus. Common name: Ragwort, Groundsel.
A genus of very uncertain circumscription, if treated broadly with as many as 1500-2000 species, trees, shrubs, herbs, and vines. The recent trend is to divide Senecio into smaller, more natural genera. Most species in our flora traditionally treated as "Senecio" are not even part of a broadly defined core group, and have been transferred to Packera, Hasteola, and Rugelia.

See something missing or incorrect about Senecio? Let us know here:
- Please include your name and if possible, email in case when need to clarify what you wrote.
- If you opt out of including email, please be as specific as possible (e.g., which photo is incorrect?)
- Please do not submit questions asking to identify plants or about horticultural topics (e.g., how do I control an invasive plant in my garden?). Instead, those questions can be submitted here for the Carolinas region only.
- Please do not send us feedback about unkeyed species as this work is ongoing.
- Please allow time for flora edits to show in our next data release. We greatly appreciate your feedback but may require extra time to research complicated taxonomic issues.
