Stanford’s Manzanita

Arctostaphylos stanfordiana ssp. stanfordiana, commonly known as Stanford’s Manzanita, is a subspecies of manzanita native to the coastal regions of California, particularly concentrated around the San Francisco Peninsula and the Santa Cruz Mountains. This evergreen shrub typically reaches a height of 1 to 3 meters (3 to 10 feet) and exhibits a dense, bushy form with a spreading habit. The bark is smooth and reddish-brown, which is characteristic of many manzanita species, and it often peels in thin sheets, adding to its ornamental appeal.

The leaves of Stanford’s Manzanita are small, leathery, and oval-shaped, measuring approximately 2 to 5 centimeters in length. They are dark green on the upper surface and lighter green beneath, often with a waxy coating that helps reduce water loss, an important adaptation to the Mediterranean climate of its native range. The plant produces clusters of small, urn-shaped flowers that are typically white to pale pink, blooming in late winter to early spring. These flowers are attractive to various pollinators, including bees. Following the flowering period, the plant bears small, round berries that are red to orange in color, which serve as a food source for birds and other wildlife.

Ecologically, Arctostaphylos stanfordiana ssp. stanfordiana plays a significant role in its native habitat by providing cover and food for various animal species. It is also a key component of chaparral and coastal scrub ecosystems, contributing to soil stabilization and preventing erosion. Human uses of this plant include its ornamental value in landscaping due to its attractive foliage and flowers, as well as its drought-resistant qualities, making it suitable for xeriscaping. Additionally, like other manzanitas, it has fire-adapted traits, such as thick bark and the ability to resprout after fire, which allows it to thrive in fire-prone environments.
