Fun Facts
- 🌱 Sweetbay Magnolia is one of the few hardy magnolia species native to eastern North America, with fossils dating back over 100 million years, making magnolias some of the oldest flowering plants.
- 🌱 The flowers bloom continuously from late spring through August, unlike many ornamental trees that flower for only a few weeks—a single tree can produce hundreds of fragrant blooms over the season.
- 🌱 The silvery undersides of the leaves are a distinctive feature caused by a waxy coating; they flutter dramatically in the breeze, creating a shimmering effect in the landscape.
