Hi Emilee,

Thank you for reaching out to us! We appreciate you being a part of our community committed to our nation's great parks and public lands. We do our best to provide the most accurate and up-to-date information for outdoor explorers like you with our free app.

This one of the more challenging questions we've encourtered so far. I reached out to our friends over at the NPS to be sure to give you the correct answer.

All of the plants you mentioned can be found in Mammoth Cave, there are several species of Devil's Shoestring, Fennell, Skullcap, Hibiscus and Lobelia, Park Rangers would have a list of locations that they could be found at. 

We hope this information is helpful, and we appreciate that you took the time to share with us. We hope you will continue using our app to find more great parks to explore! Thanks again!

Cheers!

Ron
