Allesso Elderberry

The Allesso Elderberry plant, also known as Sambucus nigra 'Allesso,' is a deciduous shrub that belongs to the Adoxaceae family. It typically grows up to 8-10 feet tall and wide, with an upright and bushy habit. The Allesso Elderberry is known for its striking foliage, which emerges as a deep purple color in the spring before transitioning to a dark green color in the summer.

The plant blooms in late spring to early summer, producing large, flat-topped clusters of creamy-white flowers that are highly fragrant and attractive to bees and other pollinators. These blooms give way to clusters of dark purple berries that ripen in late summer to early fall. The fruit is edible and commonly used to make jams, jellies, and syrups.

The Allesso Elderberry prefers full sun to partial shade and well-drained soils. It is also tolerant of a range of soil types, including clay and loam. This plant is hardy in USDA zones 4-7 and can tolerate cold temperatures down to -30°F. It is relatively low-maintenance and does not require frequent pruning, though it can benefit from occasional pruning to maintain its shape and encourage new growth.

Overall, the Allesso Elderberry is an attractive and versatile shrub that can add beauty and interest to any garden or landscape. Its stunning foliage, fragrant blooms, and edible fruit make it a popular choice among gardeners and landscapers alike.
