Rhus integrifolia, also known as lemonade sumac, [1] lemonade berry, or lemonadeberry, is a shrub to small tree. It is native to the Transverse and Peninsular Ranges and the South Coast regions of Southern California. This extends from Santa Barbara County and the Channel Islands to San Diego County and extending into north-central Pacific coastal Baja California and its offshore islands such as Cedros Island.

Contents

It is 1–8 metres (3.3–26.2 ft) in height, with a sprawling form, and is a member of the chaparral plant community often found in canyons and on north-facing slopes below elevations of 900 metres (3,000 ft). Rhus integrifolia often hybridizes with Rhus ovata .

Description

Rhus integrifolia leaves are simple (unusual in a genus where most species are trifoliate), alternating, evergreen and leathery, ranging from two to four centimeters wide on reddish twigs; length of leaves is five to seven centimeters. Leaves are toothed with a waxy smooth appearance above and a paler tone below. The flowers which appear from February to May are small, clustered closely together, and may be either bisexual or pistillate. [2] [3]

These fragrant flowers exhibit radial symmetry with five green sepals, five white to rosy-pink petals, and five stamens. The small flowers are only six millimeters across. The ovary is superior and usually has a single ovule; although in pistillate flowers, the stamens are small and infertile. The mature fruit of Rhus integrifolia is sticky, reddish, covered with hairs, and about seven to ten millimeters in diameter. The elliptical fruit presents tight clusters at the very ends of twigs.

Young plants manifest smooth reddish bark, while more mature individuals have cracked, even scaly, grayish bark with the smooth red bark displayed underneath. Twigs are rather stout and flexible, and reddish bud ends are diminutive and pointed. There is often a multi-furcate branching structure from the base of the plant. A mature plant is large and thicket-like with a sprawling arrangement.

Ecology

The lemonade berry plant is found on north and east-facing slopes and canyon floors in coastal areas of southern California and northern Baja California; however, one colony has even been observed as far north as Santa Cruz County. The lemonade berry occurs in both chaparral and coastal sage scrub communities.

This plant thrives on well-drained soils and endures heat and windy conditions well. The species tolerates sandy as well as medium loam soils, and it can even thrive in nutrient deficient soil. This plant tolerates mildly acid to mildly alkaline soils, and is common on north and east-facing slopes with where shady, moist conditions are prevalent. [4] Propagation is by seed or by rhizome. Bird species enjoy the fruits and act as a major disperser.

Lemonade berry is not frost tolerant, but will hybridize with the frost tolerant Rhus ovata (sugarbush) in the foothills of California and Mexico where their ranges overlap. [5]

Uses

Many plants within this genus are considered toxic, although some reports indicate the berries of this species can be used to make lemonade flavored drinks (hence its common name). Allergic reactions may also result from skin contact with sap from some of the genera.

Lemonade berry leaves are rich in tannins. Even though the species is evergreen, there is some leaf fall in autumn, at which time the fallen leaves may be used as a brown dye or mordant. An oil can be extracted from lemonade berry seeds; moreover, this oil achieves a tallow consistency when left to stand. Thereafter the oil can be employed to manufacture candles, which burn brightly, albeit emitting a pungent scent. The wood of mature plants is dense and hard, making it prized for wood-burning fireplace kindling.

Cultivation

Rhus integrifolia can also be used as a landscape shrub and is suitable for hedging and espalier. The plant is vulnerable to frost, but often the plant will regrow by summer, after it appears to have died from cold. The growth habit is slow to moderate and, as a garden plant, this species is quite resistant to deer, and supplies nectar and fruit for birds and nectar for butterflies. Its cultural requirements mimic its natural environment with ample drainage and little summer water.

Chaparral Shrubland plant community in western North America

Chaparral is a shrubland plant community found primarily in the U.S. state of California, in southern Oregon, and in the northern portion of the Baja California Peninsula in Mexico. It is shaped by a Mediterranean climate and infrequent, high-intensity crown fires. Chaparral features summer-drought-tolerant plants with hard sclerophyllous evergreen leaves, as contrasted with the associated soft-leaved, drought-deciduous, scrub community of coastal sage scrub, found often on drier, southern facing slopes within the chaparral biome. Three other closely related chaparral shrubland systems occur in central Arizona, western Texas, and along the eastern side of central Mexico's mountain chains (mexical), all having summer rains in contrast to the Mediterranean climate of other chaparral formations. Chaparral comprises 9% of California's wildland vegetation and contains 20% of its plant species. The name comes from the Spanish word chaparro, which translates to "place of the scrub oak".

Sumac Related species of plants in the family Anacardiaceae

Sumac, also spelled sumach, is any of about 35 species of flowering plants in the genus Rhus and related genera in the cashew family (Anacardiaceae). Sumacs grow in subtropical and temperate regions throughout the world, including East Asia, Africa, and North America. Sumac is used as a spice, as a dye, and in medicine.

Coastal sage scrub Shrubland plant community of California

Coastal sage scrub, also known as coastal scrub, CSS, or soft chaparral, is a low scrubland plant community of the California coastal sage and chaparral subecoregion, found in coastal California and northwestern coastal Baja California. It is within the California chaparral and woodlands ecoregion, of the Mediterranean forests, woodlands, and scrub biome.

<i>Adenostoma fasciculatum</i> Species of flowering plant

Adenostoma fasciculatum, commonly known as chamise or greasewood, is a flowering plant native to California and Baja California. This shrub is one of the most widespread plants of the California chaparral ecoregion. Chamise produces a specialized lignotuber underground and at the base of the stem, known as a burl, that allow it to resprout after fire has off burned its stems. It is noted for its greasy, resinous foliage, and its status as one of California's most iconic chaparral shrubs.

<i>Frangula californica</i> Species of tree

Frangula californica is a species of flowering plant in the buckthorn family native to western North America. It produces edible fruits and seeds. It is commonly known as California coffeeberry and California buckthorn.
