Fun Facts

🌱 The name 'Fireglow' perfectly describes the tree's ability to produce intensely luminous red foliage that appears to glow, especially when backlit by morning or evening sunlight.
🌱 Japanese maples have been cultivated in Japan for over 1,000 years, with hundreds of cultivars developed through selective breeding for specific foliage colors, leaf shapes, and growth habits.
🌱 Fireglow's red coloration is produced by anthocyanin pigments that increase in response to sunlight and cool temperatures, which is why fall color is typically more vibrant than summer color.
