Herbs In Action!

A weekly radio series featuring

the Botany in Action Fellows,

discussing herbs from around the world.


A program of Phipps Conservatory and Botanical Gardens, the Botany in Action Fellowship (BIA) provides PhD students from the U.S. who conduct plant-based scientific field research with funding, training and opportunities in public science engagement, placing them at different locales around the world.  BIA Fellows’ research includes ethnobotany, diversity and conservation, restoration, and sustainable landscapes, strengthening the connection between environmental and human well-being.

Through their travels, BIA Fellows encounter native species of herbs that are plentiful, have cultural or special significance, and have interesting or unusual uses.   Listen as they share their knowledge of and experiences with these herbs as botanists of the world.

Jonathan Flickinger – cuban-oregano

“Cuban Oregano”

Florida International University (FL)

Locale:  Caribbean Islands

Study:   Diversity and classification of the Myrtle Family in the Caribbean Islands Biodiversity Hotspot.

The Caribbean Islands qualify as a hotspot of biodiversity due to their wealth of unique species at risk of extinction. The myrtle family, a large group of tropical trees and shrubs, includes over 500 species in the Caribbean. Mr. Flickinger’s research aims at discovering the relationships between species in the myrtle family across the region to better understand this significant component of tropical forests.
