Fun Facts
- 🌱 Marsh myrtle has nitrogen-fixing root nodules, allowing it to thrive in poor, boggy soils where few other shrubs can survive—a natural adaptation to wetland ecosystems.
- 🌱 The plant's aromatic waxy berries were historically collected and boiled down to make 'myrtle wax' candles in Northern Europe, valued for their pleasant scent that surpassed tallow candles.
- 🌱 Despite its common name 'myrtle,' Marsh myrtle is not closely related to true myrtle (Myrtus); the name reflects historical folklore and the aromatic nature of both plants.
