Summary
Arizona wolfberry is a thorny native shrub of the Sonoran and Chihuahuan Deserts that produces abundant crops of soft, fleshy berries. Based on our taste tests, its fruit closely matches the general description of edible wolfberries. Well adapted to dry washes and desert scrub, Arizona wolfberry has long been an important seasonal food for Native Americans and remains one of the most dependable native fruit-producing shrubs of the Southwest.

Edible Uses
Arizona wolfberry is one of the finest edible shrubs of the southwestern deserts. It produces dependable crops of sweet, juicy berries that require very little preparation, tolerates harsh desert conditions, and has long served as an important traditional food resource. For desert foragers, it remains one of the most valuable native fruit-producing species, as long as berries are eaten in moderation [2-3]. The berries are edible fresh or cooked. As with all wolfberries, PFAF notes that large quantities may cause digestive upset, so eat them in moderation. You can eat ripe berries fresh, cook them into sauces, or dry them for later use. Other parts of the shrub are not considered edible [2-3]. Edibility Rating: 5 out of 5 – One of the best native desert fruits, producing reliable crops of nutritious berries [2-3]. Taste and Preparation: Arizona wolfberry was one of the species evaluated during fieldwork and closely matches the general description of edible wolfberries. The ripe berries range from orange to red and are soft, juicy, and pleasantly sweet, with a flavor reminiscent of ripe tomatoes combined with a slight citrus-rind bitterness. The numerous seeds are soft enough to be eaten with the fruit. Fresh berries are excellent eaten straight from the shrub or combined with wild onions to make fresh salsa. Cooking produces a thick, sweet, tomato-like sauce that works well in soups, stews, and other savory dishes. Because the berries spoil quickly unless refrigerated, eat them soon after harvesting or dry them for storage. Drying concentrates the sugars, producing berries that resemble raisins but taste noticeably sweeter than when fresh [2-3]. Seasonality: Arizona wolfberry flowers from late winter into early spring, with berries ripening during spring and early summer. Good fruit crops are dependable even in relatively dry years, and additional crops may develop following summer rainfall. Traditional Uses Wolfberries were among the most important native fruits available to Indigenous peoples of the Sonoran Desert, where few other fresh fruits occur naturally. People gathered the berries fresh, cooked them, and dried them for later use, providing an important seasonal food source in desert environments [2-3]. Indigenous groups, such as the Yuma (Quechan) peoples of the American Southwest and northwestern Mexico, traditionally gathered the succulent scarlet berries as an important food. Safety: Although ripe berries are edible, eat them in moderation, as large quantities may cause stomach upset. Use care when harvesting because of the sharp thorns. We recommend confirming identification before consuming any wild Lycium species [2-3].

Cultivation details
Arizona wolfberry grows best in full sun and well-drained sandy, gravelly, or rocky soils. It is exceptionally drought-tolerant and thrives in hot desert climates with minimal supplemental water. Habitat: This species occurs in desert washes, alluvial flats, rocky slopes, and desert scrub throughout Arizona, New Mexico, and northern Mexico, especially in the Sonoran and Chihuahuan Deserts. USDA Hardiness Zones: USDA Zones 8–10. Growth Rate: Arizona wolfberry has a moderate growth rate, producing vigorous new shoots after seasonal rainfall while remaining well adapted to extended drought. Mature Size: Plants typically grow 1–3 meters (3–10 feet) tall, forming dense, thorny shrubs. Cultivation: Arizona wolfberry suits native and water-wise landscapes. It requires full sun and excellent drainage and becomes highly drought-resistant once established. Its colorful berries and attractive flowers also make it valuable for wildlife. Identification: Arizona wolfberry is a thorny shrub with small, fleshy leaves borne singly or in clusters along the branches. It produces pale purple, tubular flowers with exserted (protruding) stamens, followed by soft orange-to-red berries containing numerous small seeds. The protruding stamens help distinguish this species from several other southwestern wolfberries. Similar Species: Arizona wolfberry resembles Anderson's wolfberry (Lycium andersonii), Berlandier's wolfberry (L. berlandieri), Baja wolfberry (L. brevipes), Fremont's wolfberry (L. fremontii), pale wolfberry (L. pallidum), and Torrey's wolfberry (L. torreyi). These soft-fruited species share very similar edible characteristics, although L. exsertum is distinguished by its prominently exserted stamens.
