Silverberry (Elaeagnus umbellata), also known as Autumn Olive, is a widespread shrub found in various environments, from disturbed areas to forest edges. It is notable for its silvery foliage and abundant fruit production. Many people are unaware of its potential as a food source. This article explains how to identify and utilize this plant.
Identifying Silverberry
Accurate identification of silverberry is important. Its leaves are typically elliptical to oblong, 2 to 4 inches long, with a distinctive silvery or grayish-green upper surface and a densely silver-scaled underside. This silvery sheen gives the plant its common name. The shrub usually grows as a dense, rounded form, reaching 6 to 15 feet tall.
Small, fragrant, bell-shaped flowers appear in clusters during spring, ranging from cream to pale yellow. These are followed by the development of berries. The most distinguishing feature for identification is the fruit: small, round berries, approximately 0.25 inches in diameter, which ripen from silvery-yellow to a vibrant red, often retaining unique silver or brown speckles.
Edible Parts and Safety Considerations
The primary edible part of the silverberry plant is its fruit. These berries are best consumed when fully ripe, typically turning a deep red and becoming soft to the touch. Unripe berries are astringent due to high tannin content, creating a puckering sensation, but they are not toxic. As they ripen, their flavor transforms from tart to a sweet-tart profile. Each berry contains a single, relatively large seed.
While berries are the most common edible component, the fragrant flowers can also be used. They are sometimes used to make infusions or for flavoring, offering a delicate aroma. Silverberry is not known to be toxic to humans. However, as with any foraged food, ensuring correct identification is important to avoid consuming other, potentially harmful plants.
Harvesting and Preparation
The optimal time to harvest silverberry fruits is from late summer into fall, generally August to October, when they are fully ripened and soft. Ripe berries detach easily from the stems, indicating readiness. Some foragers lay a tarp or sheet beneath the shrub and gently shake the branches, allowing the ripest berries to fall. This method helps collect a good quantity quickly and ensures only truly ripe fruits are gathered.
After harvesting, wash the berries thoroughly to remove dirt or debris. Remove any small stems or leaves. The berries contain a single seed, which can be consumed, though it is often discarded due to its fibrous texture. For many culinary applications, processing the berries through a food mill effectively separates the pulp from the seeds.
Culinary Uses and Recipes
Silverberry fruits offer a unique sweet-tart flavor, making them versatile in the kitchen. They can be enjoyed fresh as a snack, especially when fully ripe. The berries are excellent for making preserves like jams and jellies, where their tartness is balanced by added sugar.
Beyond preserves, silverberry can be incorporated into various baked goods, including pies, tarts, and quick breads, adding a distinctive fruity note. The pulp, obtained by processing the berries, can be used for fruit leathers or sauces. For beverages, the juice can be extracted for smoothies or as a flavorful base for sodas. The subtle, fragrant flowers can also infuse teas or flavor desserts.
