Fun Facts
- 🌱 Purple Japanese Maples are not naturally purple; the 'Bloodgood' cultivar was developed in Japan and takes its name from Bloodgood Nursery in New York, where it was popularized in the 1960s.
- 🌱 Despite their delicate appearance, Japanese Maples can live 100+ years, making them valuable long-term landscape investments that can be passed down through generations.
- 🌱 The distinctive two-winged seeds (samaras) are designed to helicopter-spin as they fall, allowing them to disperse over greater distances from the parent tree.
