Which species is also called Cascades Mahonia?

Cascades Mahonia is the common name for Mahonia nervosa. This species is native to the Pacific Northwest region and is adapted to the understory environments typically found in forested areas. It features holly-like leaves and produces yellow flowers in the spring, which are followed by blue-black berries. Mahonia nervosa is particularly valued as an ornamental plant due to its evergreen foliage and ability to thrive in shady conditions, making it a popular choice for landscaping in areas where other plants might struggle.

The other options list different species that do not share the common name of Cascades Mahonia. For instance, Mahonia aquifolium, commonly known as Oregon grape, is related but not the same plant. Leucothoe axillaris and Ilex aquifolium refer to entirely different plant families and have their own distinct characteristics and uses. Understanding the specific names and common names of plants is crucial in horticulture for proper identification and cultivation practices.
