Lonicera involucrata, also known as Bearberry Honeysuckle, Twinberry Honeysuckle, Twin-berry, or Black Twinberry, is a species of honeysuckle native to northern and western North America. It can be found from southern Alaska to Quebec in Canada, and south through the western United States to California, and even in northwestern Mexico.

This deciduous shrub can grow up to 1.2 m (4ft) at a medium rate. It is hardy to zone 4 and can tolerate a variety of soil types, from light and sandy to medium and loamy, and even heavy clay. However, it does not thrive in shade and prefers moist soil conditions. While it can tolerate strong winds, it is not suitable for maritime exposure.

In May, Lonicera involucrata produces yellow, tubular flowers that are hermaphrodite and are pollinated by insects. The flowers are followed by black berries, 6-12 mm in diameter, containing several small seeds. This plant is more commonly used as an ornamental due to its resistance to air pollution and its suitability for large gardens.

It is important to note that this species of honeysuckle may have varying levels of edibility and palatability, and in some cases, it may even be poisonous.
