Korser Elderberry

The Korser elderberry plant, also known as the Black Lace elderberry, is a deciduous shrub that typically grows to a height of 6-8 feet (1.8-2.4 meters) and a spread of 4-6 feet (1.2-1.8 meters). It is a popular ornamental plant that is prized for its striking dark foliage and clusters of fragrant, pink flowers that bloom in late spring to early summer.

The leaves of the Korser elderberry plant are deeply cut and have a lacy appearance. They are a rich, dark purple-black color that contrasts beautifully with the pink flowers. The plant produces small, deep purple-black berries in the late summer that are edible but not commonly eaten as they can cause stomach upset if not cooked properly.

The Korser elderberry plant prefers moist, well-drained soil and full sun to partial shade. It is a hardy plant that can tolerate cold temperatures and is generally resistant to pests and diseases. Pruning can be done in the winter or early spring to promote new growth and maintain its shape.

This plant is often used as a focal point in gardens and landscapes, and can also be planted in large containers on patios or decks. It is also attractive to pollinators such as bees and butterflies, making it a beneficial addition to any garden.
