Salal is a small, evergreen shrub native to the Pacific Northwest region of North America. Known for its dark blue or purple berries, salal is a favorite among foragers and chefs alike.

The plant is prized not only for its culinary uses but also for its potential health benefits, including antioxidant properties and the ability to support immune health. Salal berries have long been an important food source for indigenous people in the Pacific Northwest, where they have been used in various dishes, from jams to desserts to traditional medicinal preparations. In modern times, salal berries have gained attention for their versatile flavor profile and their role in natural health remedies.

History of Salal

Salal has a rich history, particularly in the indigenous cultures of the Pacific Northwest. Native tribes such as the Haida, Tlingit, and Coast Salish have long relied on salal berries as a key part of their diet. The berries were often harvested in the summer and preserved for use during the winter months. Indigenous people would dry the berries, mash them, or use them to make a variety of foods, including cakes, puddings, and sauces.

The salal plant itself has been valued for more than just its fruit. The leaves were sometimes used to make medicinal teas, and the plant’s strong, flexible stems were used for weaving baskets. Today, salal remains an important part of the local ecosystem and continues to be celebrated for its edible berries.

Botanical Description

Salal is a small, evergreen shrub that typically grows to about 30–90 cm (12–36 inches) in height. It has leathery, dark green leaves that are elliptical or ovate in shape. The plant produces small, bell-shaped white or pink flowers in the spring, which are followed by the dark purple or blue berries in late summer and fall. These berries are often covered in a waxy coating that gives them a shiny, attractive appearance.

The plant grows in shady, moist environments, often found in coastal forests, woodland areas, and under the canopy of larger trees. It can thrive in acidic, well-drained soils and typically prefers cool, temperate climates.

Growing Instructions

Salal is a hardy shrub that can be grown in a variety of conditions, though it has specific requirements to flourish. Here's how to successfully cultivate salal.

Sunlight: Salal does best in partial to full shade. While it can tolerate some direct sunlight, it thrives in the shade, particularly under the canopy of larger trees, which is why it’s often found in forested areas. The ideal location should provide light dappled by overhead tree branches, though it can also grow in more open spaces with some protection from the harsh midday sun.

Soil: Salal prefers acidic, well-drained soils, typically with a pH range of 5.0–6.0. It is often found in the wild in soil rich in organic matter, such as the forest floor under coniferous trees. A slightly loamy, moist soil mixture works well, but the plant can adapt to various soil types as long as they drain well. It’s important to avoid heavy clay soils that retain too much water.

Temperature: Salal is native to temperate climates, making it suitable for USDA hardiness zones 6 through 9. It prefers cool to mild temperatures and is tolerant of frost. However, it may struggle in regions where winters are excessively cold or summers are too hot. It can tolerate coastal breezes and the mild, damp conditions often found near the Pacific Ocean.

Watering: Salal needs consistent moisture, especially during its active growing season in the spring and summer. It prefers moist, well-drained soil but does not like to be waterlogged. If planting salal in a garden, it’s important to water the plant regularly, especially during dry periods, but be sure that the soil doesn’t become too soggy. Mulching around the base of the plant can help retain moisture and keep the roots cool.

Spacing: If planting multiple salal shrubs, space them about 60 cm (24 inches) apart. This gives them enough room to grow and spread without overcrowding. Salal has a tendency to form dense thickets, so planting them too close together could limit airflow and lead to disease or pest issues.

Pruning: Salal is generally low-maintenance, but it benefits from occasional pruning. Pruning helps maintain the shrub’s shape, remove dead or diseased branches, and encourage the growth of new shoots. Cutting back the older, woody branches also allows light to reach the interior of the plant, which can help it produce more berries.

Support: While salal is a low-growing shrub, providing some support during its early growth stage can help it establish a strong root system. Salal tends to grow in a spreading fashion, but if you're growing it in a more open area, you may want to provide a small trellis or support to keep it upright, though it typically doesn’t require much assistance once established.

Life Cycle: Salal follows a perennial life cycle, meaning it lives for many years and will continue to produce fruit each season. Here’s a breakdown of the plant's growth stages:

• Germination: Salal can be propagated through seeds or cuttings. Seeds typically take a few months to germinate and need to be cold-stratified (exposed to cold temperatures) for about 3 months before planting.

• Vegetative Growth: Once the seeds or cuttings are planted, salal will spend the first year or two establishing its root system and producing new shoots. During this time, it will form its leathery, evergreen leaves and develop its bushy growth habit.

• Flowering: In the spring, salal produces small, bell-shaped flowers that are usually white or pink. The flowers attract pollinators like bees and butterflies. Flowering occurs in late spring, and the plant may take a few years to produce a substantial amount of berries, depending on the growing conditions.

• Fruit Set: Salal’s berries are dark purple to blue in color and are ready to harvest in late summer or early fall. The berries are surrounded by a waxy coating and have a sweet, slightly tart flavor.

• End of Season: Salal is a hardy shrub that remains evergreen throughout the winter, and the plant continues to thrive year after year. After the berries are harvested, the plant goes dormant in the colder months.

Harvesting and Foraging

Harvesting: Salal berries are typically ready for harvest in late summer to early fall. The berries should be fully ripe, which means they should have a deep purple to blue color and be slightly soft to the touch. Use a gentle hand when harvesting to avoid damaging the delicate berries.

Foraging: In the wild, salal can be foraged from forests, woodlands, and coastal regions where the plant grows naturally. It is important to be aware of local regulations around foraging, as some areas may have restrictions on the harvesting of wild plants.

Plant Companions

Salal grows well alongside other plants that enjoy shade and acidic soil conditions. Some beneficial plant companions include:

• Ferns: Many types of ferns thrive in the same environments where salal grows.

• Rhododendrons: Rhododendrons also prefer acidic soil and shade, making them ideal companions for salal.

• Huckleberries: Both salal and huckleberries share similar growing conditions and can thrive together in woodland environments.

Common Pests and Diseases

Pests: Salal is relatively pest-resistant, but it can still fall victim to a few common garden pests, such as:

• Aphids: These tiny insects can be found feeding on the tender new growth. Use insecticidal soap or natural predators like ladybugs to control aphid populations.

• Spider Mites: These pests can cause stippling and yellowing of the leaves, weakening the plant.

• Slugs and Snails: These pests are attracted to the plant’s leaves, especially in moist conditions.

Diseases: Salal is generally quite healthy, but it can occasionally suffer from fungal diseases, including:

• Powdery Mildew: This fungal disease causes a white, powdery coating on the leaves and stems. It is often a problem in areas with poor air circulation or high humidity.

• Root Rot: Root rot is often caused by overwatering or poor drainage.

Shopping Tips

When purchasing salal berries, look for plump, dark purple or blue berries that are not overly soft or wrinkled. If purchasing them in processed forms such as jam or syrup, check the ingredients to ensure they are made with minimal added sugars and preservatives.
