Prunus lyonii, commonly known as the Catalina Island cherry or the Catalina mahogany, is a species of flowering plant in the Rosaceae family. It is a small to medium-sized evergreen tree or shrub that is native to the Channel Islands of California, particularly Santa Catalina and San Clemente Islands.
The Catalina Island cherry typically reaches a height of 20 to 40 feet (6 to 12 meters), with a spread of around 15 to 20 feet (4.5 to 6 meters). It has a dense, rounded canopy with glossy, dark green foliage. The leaves are elliptical to lance-shaped, measuring 3 to 5 inches (7.5 to 12.5 cm) long.
In spring, this species produces attractive clusters of small, fragrant, white flowers with five petals. These blossoms give way to small, round fruits that mature from green to reddish-black. The fruits are edible and have a tart flavor that can be used for making preserves or consumed fresh.
Prunus lyonii is highly valued for its ornamental attributes, making it a popular landscaping choice. It thrives in a wide range of soil types, performing best in well-draining sandy or loamy soils. It prefers full sun exposure but can tolerate partial shade.
This species is admired for its ability to withstand coastal conditions, including strong winds and salt spray, which makes it well-suited for coastal gardens and seaside communities. It also attracts pollinators, such as butterflies and bees, adding to its ecological value.
