Urban Ecology
Madagascar Periwinkle, a common garden plant in Florida, is also the source of vincristine and vinblastine — two chemotherapy drugs used to treat childhood leukemia — so tracking where it spreads outside gardens helps researchers and land managers monitor its footprint.
Someone walking the Tortuga Trail in Boca Raton spotted a Madagascar Periwinkle — a pretty pink-flowered plant you've probably seen in garden beds or pots. The sighting was confirmed as research-grade on iNaturalist, meaning the ID is solid. While it's a beloved garden plant, it can escape cultivated areas and pop up in natural spaces, which is worth keeping an eye on.
