The ripe fruits are the only food part worth considering. They should be eaten only when fully ripe and only in small quantities. Unripe fruits are unpleasant and should be avoided. The fruit has been suggested as a substitute for true olive in some edible-plant references, but other sources describe it as bitter or generally inedible, so caution is warranted [2-3]. Edible Uses & Rating: Desert olive ranks as a low-to-moderate wild fruit. The best ripe fruits can be sweet, juicy, and fruit-like, but bitterness and uncertainty reduce its value. It is not a staple fruit and should not be eaten in large amounts. A fair rating would be 2/5 for food value, mainly because the fruit can be pleasant but remains questionable and minor [2-3]. Taste, Processing & Kitchen Notes: Fully ripe fruits are small, dusty, bluish-purple to purple-black drupes with thin flesh around a soft pit. The flavor may combine sweetness, moderate bitterness, and a faint olive-like quality, though it is fruitier than that of cultivated olives. Cooking does not significantly improve the fruit, and unripe fruit remains poor even after cooking. The best use is cautious fresh sampling of fully ripe fruits from productive shrubs. Processing into sauces, relishes, or olive-like preparations would be experimental [2-3]. Seasonality (Phenology): Desert olive flowers from late winter into spring, often February to May, before or as leaves appear. Fruits mature from mid-summer into autumn. A USDA NRCS fact sheet notes that stretchberry is dioecious, blooms in late March to mid-April in Montana trial conditions, and its dark bluish-black fruits mature in late August to September, with fruit often taken by birds before falling. Safety & Cautions (Food Use): Use caution. The fruits are probably nontoxic in small amounts but are often described as inedible or of minor value. Only fully ripe fruits should be sampled. Avoid meal-sized consumption, especially because the fruit’s limited traditional use suggests it was not considered an important or consistently safe food. Do not consume leaves, bark, or other plant parts as food [2-3]. Harvest & Processing Workflow: Harvest only fully ripe, bluish-purple or purple-black fruits that detach easily and taste sweet enough to justify use. Avoid green, hard, or strongly bitter fruits. Remove debris, rinse, and sample in small quantities. Because birds readily eat the fruit, the harvest window may be brief. Leave plenty for wildlife. Cultivar/Selection Notes: No food cultivars are widely known. For native landscaping, female plants are needed for fruit, and male plants are needed nearby for pollination because the species is often dioecious. Selection for gardens usually focuses on drought tolerance, early bloom, wildlife value, and screening form rather than fruit quality. Look-Alikes & Confusion Risks: Desert olive may be confused with privets, olives, or other opposite-leaved shrubs. The early petal-less flowers, opposite narrow leaves, often spine-tipped branches, and small purple-black drupes help identify it. It should not be confused with true olive, Olea europaea, which has a very different fruit chemistry and long-established food-processing methods [2-3]. Traditional/Indigenous Use Summary: Documented Indigenous food use appears limited. The fruits were reportedly eaten occasionally by Apache people, but they did not form an important food. This limited use is one of the main reasons to treat desert olive as a cautious minor fruit rather than a recommended staple [2-3].

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.


Desert Olive (Forestiera pubescens var. pubescens) is primarily a landscape and wildlife plant. While its leaves were used in some traditional Native American ceremonial practices as an emetic to induce vomiting, the plant has no widely recognized modern medicinal uses.

Ecology & Wildlife: Desert olive is valuable for birds and wildlife. The fruits are eaten by birds and may disappear before they fall, while dense branching provides cover and nesting structure. The shrub is useful in wildlife-friendly hedgerows and low-water native plantings. It is suitable for native hedgerows, dry streambeds, canyon gardens, and wildlife plantings. Plant both male and female individuals if fruit is desired.
