Fun Facts
- 🌱 Red maple is one of the most abundant native trees in eastern North America and has expanded its range northward in recent decades, possibly due to climate change.
- 🌱 The tree gets its name from virtually all red parts: red flowers, red twigs, red seeds, and brilliant red fall foliage—earning it the nickname 'the tree that bleeds red.'
- 🌱 A mature red maple can produce over 1,000 seeds in a single year, which are dispersed by wind and float on water, allowing the species to colonize new wetland areas rapidly.
