Prunus ilicifolia (Common names: hollyleaf cherry, [4] evergreen cherry; [5] islay - Salinan Native American [6] ) is native to the chaparral areas of coastal California (from Mendocino County to San Diego County), Baja California, and Baja California Sur. [5] [7] as well as the desert chaparral areas of the Mojave desert. [8] [9]

Contents

Prunus ilicifolia is an evergreen shrub [4] to tree, producing edible cherries, with shiny and spiny toothed leaves [4] similar in appearance to those of holly. This resemblance is the source of both the common name "holly-leaved cherry" and the scientific epithet "ilicifolia" (Ilex-leaved). It grows 2.4 to 9.1 metres (8 to 30 feet) tall, with thick, alternate leaves 2.5 to 5.1 centimetres (1 to 2 inches) in length. [4] It has small white flowers growing in clusters, similar in appearance to most members of the rose family, Rosaceae, flowering from March to May. [4] The flowers are terminal on small stalks, with the youngest at the cluster center. The purple to black fruit is sweet, with a very thin pulp around a large single stone (drupe). [4] [10]

The plant is prized for cultivation, showy and easily grown from seed, and has been cultivated for centuries as a food source, and tolerates twice yearly pruning when often used as a hedge. [4] The plant likes full sun, loose open soil (porous), and tolerates drought conditions well, but needs regular watering when young. [4]

Despite its name, it is not a true cherry (P. subg. Cerasus) species. It is traditionally included in P. subg. Laurocerasus, but molecular research indicates it is nested with species of P. subg. Padus. [11] Ilicifolia or “ilex foliage,” means “holly-like leaves” in Latin [4]

Prunus ilicifolia flowers

It is an evergreen shrub [4] or small tree approaching 15 metres (49 feet) in height, [12] with dense, hard leaves [4] (sclerophyllous foliage). The leaves are 1.6–12 centimetres (344+34 inches) long with a 4–25 millimetres (18–1 in) petiole [12] and spiny margins, somewhat resembling those of the holly. The leaves are dark green when mature and generally shiny on top, and have a smell resembling almonds when crushed; these are poisonous to eat, but not to handle. [13] The flowers are small (1–5 mm), white, produced on racemes in the spring. The fruit is a cherry 12–25 mm in diameter, sweet in taste, with little flesh surrounding the smooth seed. [12] [14] [15]

Subspecies

There are two subspecies: [16] [17] [18]

Distribution and habitat

Prunus ilicifolia is native to California chaparral and foothill woodlands along the Coast Ranges below 1,600 m (5,200 ft). [12] Its distribution extends from northern Baja California along the California coast to the northernmost extent of the Coast Ranges, [12] as well as into the desert chaparral areas of the Mojave desert. In chaparral communities, it tends to inhabit north-facing slopes, erosion channels, or other moist, cool sites. [5] This is the only species of the genus Prunus native to California's Santa Monica Mountains, which divide the Los Angeles Basin from the San Fernando Valley. [4]

It is a persistent member of chaparral communities, being slow-growing but long-lived; common chaparral flora associates are toyon, western poison-oak and coffeeberry. [19] In the absence of fire, P. ilicifolia will outlive or outshade surrounding vegetation, making room for seedlings. Eventually, it will form extensive stands codominated by scrub oak. [5]

Ecology

Although it will resprout from the stump after fires, the seeds are not fire-adapted like those of many other chaparral plants. [20] Instead, it relies on the natural death of surrounding vegetation during long periods of fire-free conditions to make room for its seedlings. [5]

Though the seeds are often reported to require sunlight to germinate, [20] germination rates of nearly 100% have been achieved with wild-collected seed buried completely in pots with a peatlite mix. [21]

The caterpillars of the pale swallowtail ( Papilio eurymedon ) feed on this and other members of the riparian woodland plant community. [18] It is also a larval host to the California hairstreak, Lorquin's admiral, Nevada buckmoth, and western tiger swallowtail. [22] Bees are attracted to it. [4]

Cultivation

Prunus ilicifolia is used in California native plants and wildlife gardens, and drought-tolerant sustainable landscaping. [23]

Uses

The pulp of the cherry is edible. [4] However, the seeds of the hollyleaf cherry are considered to be toxic, and the plant must undergo certain leaching processes to make it safe for consumption. [24] Native Americans fermented the fruit into an intoxicating drink. [4] Some also cracked the dried cherries and made meal from the seeds after grinding and leaching them. [25] It has also been made into jam. [26]

The method of preparation for the cherry was to first extract and crush the kernel in a mortar, and the resulting powder would then be leached in order to eliminate remaining bad chemicals. The final step was to boil the leached powder into an atole. [24] Once this process was completed, Native Californians would then make soup base, tortillas, or tamale-like foods using the resulting ground meal. Other times, the kernel would be kept whole, leached to remove its hydrocyanic acid content, roasted for a couple hours, and then used to make cakes or balls. [27]

Aside from food, the hollyleaf cherry was also used for medicinal purposes by some Native Californian tribes, including the Diegueño and the Cahuilla. Specifically, infusions made from the bark and roots of hollyleaf cherry plants would be used as treatment for common colds and coughs. [27]

<span class="mw-page-title-main">Cherry</span> Fruit of some plants of the genus Prunus

A cherry is the fruit of many plants of the genus Prunus, and is a fleshy drupe.

<i>Prunus</i> Genus of trees and shrubs

Prunus is a genus of trees and shrubs in the flowering plant family Rosaceae that includes plums, cherries, peaches, nectarines, apricots, and almonds. The genus has a cosmopolitan distribution, being native to the North American temperate regions, the neotropics of South America, and temperate and tropical regions of Asia and Africa, There are 340 accepted species. Many members of the genus are widely cultivated for their fruit and for decorative purposes. Prunus fruit are drupes, or stone fruits. The fleshy mesocarp surrounding the endocarp is edible while the endocarp itself forms a hard, inedible shell called the pyrena. This shell encloses the seed, which is edible in some species, but poisonous in many others. Besides being eaten off the hand, most Prunus fruit are also commonly used in processing, such as jam production, canning, drying, and the seeds for roasting.

It is a burl-forming, evergreen shrub with leathery leaves and smooth dark reddish bark. From December to February, white to pink urn-shaped flowers adorn the foliage, often attracting hummingbird pollinators. It is native to southern California and the Baja California Peninsula, south to the Sierra de la Giganta. There is growing concern over the future of this plant, referred to as the "queen of the elfin forest, " as it may possibly lose up to 88% of its habitat and its wild seedlings are failing to survive more than a full year.
