What are the purple trees along the highway in North Carolina?
The vibrant purple trees often seen along highways in North Carolina are typically the Eastern Redbud (Cercis canadensis). This native species is one of the earliest to bloom in the spring, signaling the arrival of warmer weather with its striking purple-pink flowers.
The Eastern Redbud: A Native Spring Spectacle
The Eastern Redbud, scientifically known as Cercis canadensis, is a highly recognizable and cherished native tree in North Carolina. Its prolific pea-like flowers emerge directly on the branches and even the trunk before the leaves appear, creating a breathtaking display of color.
Key characteristics of the Eastern Redbud include:
- Early Bloomer: It's among the very first trees to flower in North Carolina each spring.
- Distinctive Flowers: Small, showy, and abundant purple to pinkish-purple flowers that grow in clusters.
- Heart-shaped Leaves: After the blooms fade, attractive heart-shaped leaves unfurl, providing summer shade and turning yellow in the fall.
- Native Habitat: Naturally found in woodland edges and open areas throughout the eastern United States, including North Carolina.
Why They Thrive by Roadsides
Eastern Redbuds are commonly observed along roadsides and highway corridors due to their adaptability to certain environmental conditions. Their purple flowers adorn woodland edges and they can flourish in "disturbed roadside habitats," making them a familiar sight for travelers. Their ability to tolerate a range of soil types and their preference for full sun to partial shade contributes to their prevalence in such visible locations.
Here's a quick look at the Eastern Redbud's attributes:
