What Is Correa Glabra and Why Is It Used as a Hedge?
Correa glabra is an evergreen shrub classified as “rock correa,” a group adapted to rocky, well-drained environments. Botanically part of the Rutaceae family, it differs from other correa plant varieties by its smoother foliage and more upright growth habit. Correa glabra belongs to the Correa genus, a group of Australian native shrubs known for their tubular flowers (see Correa plant genus on Wikipedia for botanical classification).
This species naturally occurs in regions such as the Coliban River area, where it thrives in dry, exposed conditions. Compared to other correas, it is more tolerant of poor soils and less prone to fungal issues.
Correa glabra is widely used as a hedge because it forms dense foliage, maintains structure year-round, and tolerates pruning well. Its resilience to drought and wind also makes it ideal for low-maintenance landscaping.
