Fun Facts

🌱 Loblolly Bay is native only to the southeastern coastal plain and pocosins of the United States, making it a unique regional native tree with limited natural range.
🌱 The flowers are exceptionally fragrant, especially in the evening and early morning, and can fill a large garden with sweet perfume during the long blooming season from July through October.
🌱 Despite its name reference to 'loblolly' (a low-lying wet area), Loblolly Bay actually tolerates a wide range of moisture conditions from wet bottomlands to well-drained uplands, making it more adaptable than its name suggests.
