Coastal/Wild Allamanda, Pentalinon luteum

“This is a perennial vining plant that is common throughout much of the northern two-thirds of Florida in moist to seasonally wet habitats. It dies back to the ground each winter and reestablishes itself by spring. This species is a twiner, without tendrils, and it twines itself throughout the adjacent vegetation for many feet in all directions once it’s established.” – Craig Hugel, Hawthorne Hill Wildflowers. Larval host for mournful thyris.
