This lovely vine has been blooming in the Gainesville area now for a couple of weeks. All parts of the plant including the nectar are toxic to humans and honeybees. This plant was living happily (despite temps in the 30s and frost) among tall oak trees on the west side of Celebration Pointe in Gainesville, Florida. Wikipedia points out that the toxin may actually benefit bumblebees suffering from parasites.https: //en.wikipedia.org/wiki/Gelsemium_sempervirens
