Elderberry

Elderberry (Sambucus nigra) dried berries sell for $10-20/lb in the wellness and supplement market (USDA AMS Specialty Crop Market News, 2023). The plants are perennial shrubs that reach full production in year three and continue for 15-20 years. Before everything else, one fact: raw elderberries, seeds, and all green parts of the plant are toxic and must not be eaten uncooked. Cooking destroys the cyanogenic glycosides that cause nausea and vomiting. This is not a warning to add at the end - it’s the central operating fact of growing elderberries.

What you’re actually growing

American elderberry (Sambucus nigra subsp. canadensis) is native to eastern North America and the primary species grown domestically. European elderberry (Sambucus nigra subsp. nigra) is the species used in most European culinary traditions and produces flowers more prized for elderflower cordial. Both are Sambucus nigra and share the same toxicity profile for raw plant material.

The shrub grows 8-12 feet tall in full production, with large compound leaves and flat-topped clusters (corymbs) of tiny white flowers in June followed by dark purple-black berries in August through September. A single shrub does not self-pollinate well - plant two varieties for reliable fruit set. Common paired varieties include ‘Bob Gordon’ and ‘Adams 2,’ or ‘Nova’ and ‘York.‘

The ROI case

A rooted cutting at $5.99 produces a small crop in year two. Full production begins year three: 5-12 lb of fresh berries per shrub per year is typical for mature named varieties (University of Missouri Extension, Growing Elderberries, 2015). At $8/lb fresh (USDA AMS, 2023), a single mature shrub returns $40-96 per season. Two-shrub minimum for good production.

Dried elderberries concentrate the value substantially. Fresh berries reduce to roughly 25-30% of their weight when dried, which means $10-20/lb for dried product translates to $2.50-5.00/lb for the fresh equivalent. If you’re drying and selling, the gross value per pound of fresh output rises to match the dried price range.

Elderflower cordial is a separate market. Flowers harvested before the berries form sell for $8-15 per pound fresh at specialty markets, and concentrated elderflower cordial retails for $12-20 per 500ml bottle in natural food stores. Harvesting all flowers eliminates berry production that season on the harvested branches.

Growing requirements

Elderberries are adaptable. They tolerate heavy clay, periodic flooding, and significant shade better than most fruits. Full sun drives maximum berry production, but 4-6 hours of direct sun produces an acceptable crop. They are native to woodland edges and stream banks - that tells you something about their tolerance for difficult conditions.

Cold hardiness to zone 3. American varieties are the most cold-hardy; European types tend toward zones 5-6 minimum.

Soil pH 5.5-6.5. Elderberries fix no nitrogen themselves but respond well to organic matter. Annual compost mulch 3-4 inches deep around the base of the shrub improves both fertility and moisture retention.

Plant 6-8 feet apart in rows 10 feet apart for managed production. For home use, allow wider spacing - the shrubs get large. Prune in late winter, removing all canes older than 3 years at ground level. New canes emerge from the base each year; these will produce in years two and three of their life, then productivity declines. Keeping a rotation of young canes is the management principle.

What goes wrong

Elderberry borer (Desmocerus palliatus) is a metallic blue-green beetle whose larvae tunnel through the pith of elderberry canes. Infested canes wilt and die from the center outward. Cut affected canes below the damage and dispose of them - do not compost. There is no effective spray treatment for the borer once inside the cane.

Aphids cluster heavily on elderberry, particularly on new growth in spring. Large colonies cause leaf curl but rarely threaten the plant long-term. Natural predator populations (ladybugs, parasitic wasps) typically bring colonies under control by midsummer without intervention. Insecticidal soap handles severe infestations if needed.

Powdery mildew (Podosphaera* spp.) appears on leaves and new growth in dry summers with warm days and cool nights. It looks bad but rarely causes permanent harm to an established shrub. Improve airflow through pruning and avoid overhead irrigation.

Bird pressure on ripe berries is substantial. Net the clusters as they approach ripeness or harvest entire clusters slightly early and finish ripening indoors - though fully ripe off-vine berries do not keep well.

Harvest and storage

Harvest entire corymbs (flat-topped clusters) when the majority of berries are dark purple-black and soft. At this stage, tasting a berry raw to check ripeness is safe in small amounts but the dose-response for the glycosides is imprecise - cook the berries. Strip berries from the stems with a fork over a bowl; the stems contain more of the toxic compounds than the berries and should not be juiced or cooked into the final product.

Fresh berries keep 3-5 days refrigerated. Freeze in zip-lock bags for up to a year.

To dry: spread stripped berries on dehydrator trays at 135°F for 18-24 hours until fully dry. Store in airtight containers. Properly dried elderberries will last 12-18 months.

For elderberry syrup: simmer 1 cup dried or 2 cups fresh berries with 3 cups water and spices (cinnamon, cloves, ginger) for 45 minutes, mash, strain through cheesecloth, and add 1 cup raw honey per cup of cooled strained liquid. Do not add honey to the hot liquid - heat destroys its antimicrobial compounds and this defeats the purpose most people have in mind. The syrup keeps 2-3 months refrigerated.
