Mountain holly (Ilex mucronata), also known as catberry, is a moderately sized deciduous shrub with an upright growth habit and branches that reach upward. Its bark is smooth and greyish, while its young twigs display shades ranging from purplish-red to dark brown. The foliage consists of simple leaves arranged alternately along the branches, showcasing a soft green colour in summer before turning golden yellow in the fall.

In the spring, it produces small, inconspicuous greenish-white flowers that often go unnoticed but play a crucial role for pollinators. By the end of the season, these flowers give way to bright red berries that persist throughout the winter, adding a touch of colour to snowy landscapes. Adapted to moist soils rich in organic matter, this shrub thrives in shaded or partially sunny environments, particularly along riverbanks, in swamps, or under the forest canopy.

Ecological Roles

Mountain holly plays a key role in wetland and forest ecosystems. Its spring flowers, though discreet, attract certain pollinating insects. Its bright red berries, which persist through winter, provide a valuable food source for several seed-eating bird species, including blackbirds and thrushes, which contribute to seed dispersal.

Its dense root system stabilizes moist soils, preventing erosion and maintaining soil moisture, which is especially beneficial in riparian and marshy environments. Additionally, its tendency to grow in dense clusters creates habitats and shelters for small wildlife, enhancing local biodiversity. This shrub is an excellent choice for ecological restoration in wetland environments and rain gardens, where it serves both aesthetic and ecological functions.

Mountain Holly aster seeds require cold stratification to ensure germination. See the cultivation notes below for more details.
