Bob Gordon Elderberry

Bob Gordon was selected from the wild in 1999 by farmer Robert Gordon, his wife Charlotte Cooper, and University of Missouri elderberry researcher Andrew Thomas, who encountered the plant on farmland near Osceola, Missouri. Thomas recognized its commercial potential based on cluster size, sugar content, and an unusual recumbent cyme orientation — the fruit heads hang downward when ripe, deterring birds and simplifying harvest. The University of Missouri Center for Agroforestry evaluated the selection through the 2000s as part of its specialty-crop agroforestry program, and Bob Gordon became the second improved cultivar released by that program in 2011. Its open-pollinated wild origin means no cross parentage was documented; its genetics reflect natural Sambucus canadensis variation in the Missouri River bottomlands. Field trial data from multiple Missouri locations confirmed a consistent Brix and yield advantage over Adams, York, and Nova, and the variety now serves as a parent in the university’s ongoing elderberry breeding program.

Bob Gordon performs across a wide climate envelope — zones 3 through 9 — but its Missouri bottomland origins mean it genuinely thrives under conditions many fruiting shrubs find marginal: periodic wet feet, clay-heavy soils, and high summer humidity. Soil pH between 5.5 and 6.5 keeps nutrient uptake efficient; drifting above 6.5 can induce iron chlorosis on heavier soils. The plant wants 1 to 2 inches of water weekly during fruit development, and a 3-inch organic mulch layer over the root zone moderates soil temperature, retains moisture, and reduces weed competition without the compaction that bare-cultivated rows invite. Full sun drives the highest yields, though partial shade is tolerated at the cost of some fruit load. Because Bob Gordon fruits on first-year canes, cutting the entire plant to near ground level each late winter is not only safe but actively encourages the flush of vigorous primocanes that will carry next season's crop. Annual compost top-dressing or balanced organic fertilizer applied in early spring replaces nutrients lost to heavy cropping and supports the fast regrowth the variety demands.

How to Prune: Cut to ground level in late winter/early spring; remove canes older than 3 years; Bob Gordon fruits on first-year wood so hard annual pruning is acceptable

Bob Gordon develops as a multi-stemmed arching shrub, reaching 6 to 8 feet tall and equally wide under typical garden conditions, though crowded or shaded plants can push taller. Its shallow, fibrous root system spreads aggressively via underground runners, forming colonies over time — a trait that makes it excellent for erosion control along streambanks but means permanent edging or annual sucker removal is necessary when planting near lawns or paths. Individual canes complete their productive life in three to four years; a managed planting maintains 5 to 8 canes per stool, retiring the oldest wood annually and allowing new primocanes to replace it. The fast growth rate — characteristic of the species — means gaps from hard pruning close within a single season. Creamy white flower corymbs up to 12 inches across appear mid-June through mid-July, carrying a light lemon fragrance attractive to native bees and beneficial insects before giving way to the heavy berry clusters that define this variety's commercial appeal.

Growth Rate: Fast
Foliage Type: Deciduous

Bob Gordon is partially self-fertile — it will set some fruit without a cross-pollinator — but yield data from University of Missouri trials consistently shows that pairing it with a second Sambucus canadensis cultivar blooming at the same time increases fruit set noticeably. Blooms open mid-June through mid-July in a temperate climate, coinciding with most other American elderberry cultivars. Both wind and insect pollinators contribute to fruit set, so placing companions within 50 to 60 feet ensures adequate pollen transfer by both vectors. Wyldewood Elderberry and York Elderberry bloom concurrently and are proven companions in commercial plantings. Adams Elderberry also overlaps reliably and adds productive diversity to a mixed hedge or food forest planting.

Bloom Season: Very Late
Bloom Window: Mid Jun - Mid Jul
Pollination Requirements: Partially self-fertile; cross-pollination with another Sambucus canadensis cultivar significantly improves fruit set and yield; plant at least two cultivars within 50-60 feet
Pollination Mechanism: Wind and insect
Flower Color: Creamy white

The berries ripen dark purple to near-black, measuring about 0.25 inch in diameter and carried in large, flat-topped corymbs that invert slightly at maturity — a structural trait that reduces shattering during harvest and makes Bob Gordon easier to strip by hand or by machine than varieties with upright clusters. Brix readings are higher than Adams, York, and most other commonly grown cultivars, translating to a richer, sweeter-tart juice that requires less added sugar in syrup and cordial production. Fresh storage life is short — one to two weeks refrigerated — so processing promptly is standard practice. Juice, syrup, wine, and cordials are the primary commercial outputs; the flowers harvested in June and July have their own market as elderflower cordial, fritters, and herbal tea. Raw and unripe berries contain cyanogenic glycosides and should not be eaten; heat from cooking or juicing breaks down the compounds and makes the fruit safe. Yield of 20 to 35 pounds per plant at maturity puts Bob Gordon at the top of the species for productive output per planting space.

Ripening Season: Late
Harvest Window: Mid Aug - Mid Sep
Fruit Size: 0.25 inch
Flavor: Rich, sweet-tart; higher sugar (Brix) content than most elderberry varieties; well-suited for juice, wine, and syrup production

Years to Bear: 2-3 years
Yield: 20-35 per plant annually
Storage Life: Short fresh (1-2 weeks refrigerated); excellent for processing into juice, syrup, jam, wine
Culinary Uses: Juice, syrup, wine, cordials, jams, jellies, pies; flowers used in elderflower cordial, fritters, and teas; leading commercial variety for juice production

Bob Gordon reflects Sambucus canadensis's general vulnerability to fungal pathogens in humid climates. Elderberry Rust (Puccinia sambuci) appears as orange pustules on leaf undersides; removing affected foliage and avoiding overhead irrigation are the primary cultural controls. Powdery Mildew (Microsphaera sambucina) intensifies under poor air circulation — the hard annual pruning Bob Gordon needs opens the canopy and reduces mildew pressure simultaneously. Cercospora Leaf Spot (Cercospora sambucina) spreads by splash-dispersed spores; drip irrigation and fall leaf cleanup keep inoculum low. Canker diseases (Botryosphaeria spp.) colonize declining canes; retiring wood older than three years is the most practical prevention. Tomato Ringspot Virus and Cherry Leaf Roll Virus (Nepovirus spp.) are the most serious threats — certified virus-free planting stock is essential and cannot be corrected after planting. Spotted Wing Drosophila (Drosophila suzukii) targets ripe thin-skinned berries; set cider-vinegar traps four to six weeks before harvest and pick as clusters fully color to minimize damage. Elderberry Borer (Desmocerus palliatus) lays eggs near the soil line; removing infested canes at annual pruning disrupts the cycle. Japanese Beetle (Popillia japonica) causes summer defoliation — hand-picking into soapy water during the June-July flight period is adequate. Eriophyid Mites (Phyllocoptes spp.) distort young growth in dry conditions; consistent soil moisture and removal of infested shoots prevent buildup.

• Hard-prune annually: Cut all canes to 6–12 inches from the ground each late winter. Bob Gordon fruits on first-year wood, so this aggressive reset is productive, not destructive — you lose nothing and gain a flush of vigorous primocanes.
• Plant two cultivars minimum: Despite partial self-fertility, pairing Bob Gordon with Wyldewood or York within 50–60 feet reliably increases cluster size and total yield. A single isolated planting leaves significant production on the table.
• Start with certified virus-free stock: Tomato Ringspot Virus and Cherry Leaf Roll Virus persist in the soil and are difficult to eradicate once established. Buying certified clean stock is the only reliable prevention strategy.
• Time SWD monitoring early: Set cider-vinegar traps four to six weeks before expected harvest. Catching the first adult wave lets you time harvest before infestation escalates across the entire planting.
• Manage suckers deliberately: The spreading root system is an asset for erosion control, but requires annual perimeter control if the planting footprint must stay defined. Mow or cut suckers when they emerge rather than waiting until they woody up.
