Hypericum buckleyi

Buckley’s St. Johnswort is a perennial shrub that can be easily identified by its bright yellow flowers contained in clusters. Native to the southeastern United States, it is found in sandy places in pinelands and Coastal Plain habitats. The flowers are 1-1.5 inches in diameter and contain 5-6 yellow petals; the center of the flower is covered in a cluster of prominent yellow stamens. The leaves are linear and often have glandular dots, appearing like a dotted line down the center. It is an excellent nectar source for butterflies, moths, and bees. Once established, Buckley’s St. Johnswort is drought tolerant and tolerates more heat, humidity, and drought than many of its Hypericum relatives.
