Here’s another article exploring some of California’s native plants. With a remarkable abundance of flora, California is home to over 6,500 species that play a vital role in shaping its diverse and iconic landscapes.

While hiking through the chaparral-covered hills of Southern California, from the Santa Monica to the San Bernardino and San Gabriel Mountains, you’ll encounter a rich variety of plants, each adapted to thrive in the harsh, dry conditions. Some of them will inevitably be foreign, as California’s mild Mediterranean climate is a perfect incubator for invasive species. But there are many indigenous plants (aka: endemic) that are touchstones of resilience, survivors that thrive here and help make the California chaparral ecosystem incredibly diverse and hearty. Among these is the laurel sumac, a stalwart of the coastal sage scrub, its waxy, aromatic leaves adapted to withstand the sun-baked hillsides and dry seasons that define so much of California’s natural landscape.

Laurel sumac (Malosma laurina) is a large, rounded evergreen shrub or small tree that can grow up to 20 feet tall and wide. When in bloom (late spring through summer), it gives off a strong, aromatic scent that can be very pleasant. The plant is native to southern California and Baja California, and is also found on the southern Channel Islands.

The plant is characterized by lance-shaped leaves with reddish veins and stems, adding a touch of color to the landscape. Laurel sumac has a unique ability to curl its leaves upward when exposed to extreme heat. This reduces the surface area exposed to the sun, minimizing water loss and preventing overheating. This trait has earned the plant the nickname “taco plant,” as its leaves often fold up like a taco shell. The clusters of small white flowers that bloom at the tips of its branches resemble lilac blossoms. After blooming, the small, creamy-white flowers develop into clusters of tiny, reddish-brown, berry-like fruits known as drupes. Each drupe contains a single seed and is covered with a thin, leathery skin.

Although named “laurel” for its resemblance to bay laurel, laurel sumac actually belongs to the cashew family (Anacardiaceae). This family includes other well-known plants like poison oak, mango, and pistachio, highlighting the diverse characteristics within this botanical group. Laurel sumac is a vital species in the coastal sage scrub and chaparral ecosystems, offering habitat and food for wildlife. Its berries are particularly enjoyed by songbirds, including warblers. The plant blooms from late spring to early summer, producing clusters of small, white flowers that attract various pollinators, including bees and butterflies.

After flowering, it produces small, reddish-brown fruits that are a food source for birds and other wildlife. Interestingly, the shrub’s ability to thrive in the arid conditions of Southern California, combined with its distinctive red stems and fragrant blooms, make it a key contributor to the region’s natural beauty and biodiversity.

The plant is amazingly drought-tolerant, with deep roots that allow it to access water during dry periods, making it a critical species in fire-prone environments. In fact, its ability to quickly resprout after fire is one reason it’s so prevalent in chaparral communities.

Laurel sumac is also notable for its role in traditional indigenous practices. Native peoples of the region used various parts of the plant for medicinal purposes, including treating skin conditions and respiratory ailments. Known as “ektii” by the Kumeyaay people, Laurel sumac held a prominent place in their traditional practices. The Kumeyaay are indigenous to the region that spans southern California, including San Diego County, and northern Baja California, Mexico. After childbirth, a tea or wash made from the plant was used for its soothing and medicinal properties, demonstrating its role in maternal care.

Beyond its medicinal uses, the sturdy wood of laurel sumac was utilized in construction, reflecting its practical value to the Kumeyaay. In a modern twist, the dried flower clusters of the plant have found a niche in model railroading, where enthusiasts often paint them and use them as miniature trees to create realistic landscapes.

Laurel sumac is just one of the many incredible native plant species that contribute to California’s rich biodiversity. Its abundance in some of the southern mountain ranges makes it a quintessential part of the landscape and an essential topic when exploring native flora. Stay tuned as we continue to highlight more species that make California such a unique and extraordinary place.
