Establishment
First 12 monthsYoung shrub focuses on root development and establishing framework. Foliage emerges deep purple.
Water regularly to establish deep roots. Mulch around base. Avoid heavy pruning first year.
Vegetative Growth
Years 2-3Shrub rapidly develops height and width, producing dark purple foliage on new growth. Stems are reddish-brown.
Maintain consistent moisture. Prune in late winter to shape and encourage branching. Fertilize spring and early summer.
Flowering
May-June (2-4 weeks)Flat-topped clusters (cymes) of fragrant white to pale pink flowers appear at branch tips in late spring to early summer.
Flowers attract pollinators. Do not deadhead if berry production desired. Reduce nitrogen fertilizer to avoid excessive vegetative growth.
Fruiting
July-OctoberSmall dark purple to black berries develop in drooping clusters. Berries ripen midsummer and persist through fall.
Ensure adequate water during berry development. Plant multiple cultivars for better pollination and yield. Birds will begin feeding on ripe berries.
Dormancy
November-MarchLeaves drop in fall after color change. Bare branches remain ornamental with persistent berry clusters.
Prune in late winter (February-March) before growth resumes. Remove dead, diseased, or crossing branches. Can be cut back to rejuvenate old plants.

Immune Support
MedicinalElderberries are rich in vitamin C and anthocyanins, traditionally used to support immune function and reduce duration of colds and flu. Scientific research has examined elderberry's antiviral properties. [source]
Landscape Foliage Accent
OrnamentalThe deep purple to nearly black foliage provides dramatic color contrast in mixed borders, woodland gardens, and hedgerows throughout the growing season. [source]
Bird & Pollinator Support
WildlifeFragrant flowers attract bees and other pollinators in spring; abundant berries provide critical food for migratory and resident birds in late summer and fall. [source]
Jam & Preserves
CulinaryRipe berries make deep-colored, flavorful jams, jellies, and preserves with a distinctive elderberry taste. Often blended with other berries. [source]

Harvest Tips
Berries are ripe when uniformly dark purple to black, typically late July through September. Harvest by cutting entire berry clusters and stripping berries from stems. For best flavor, wait until fully ripe. Wear gloves as berries stain. Never eat raw berries in large quantities; they're best cooked. Plant 2+ cultivars for cross-pollination and higher yields.
Fun Facts
- 🌱 Atropurpurea's foliage color is most intense in full sun; plants in shade may display more green coloration, losing the dramatic purple effect.
- 🌱 Elder wood was traditionally used to make flutes and musical instruments, and elderflowers have been used in European folk medicine for centuries.
- 🌱 The berries contain cyanogenic glycosides and should never be eaten raw in large quantities; cooking breaks down these compounds and makes them safe and more nutritious.
