Here are some key characteristics and features of Cotoneaster nummularius:
1. Appearance: This shrub is low-growing and has a spreading habit. It typically reaches a height of about 30 to 60 centimeters (12 to 24 inches) and can spread up to 1.5 to 3 meters (5 to 10 feet). The stems are arching and have a reddish-brown color.
2. Leaves: The leaves of Cotoneaster nummularius are small, round, and glossy, resembling the shape of coins or pennies, which is the origin of its common name "Pennywort Cotoneaster" or "Round-leaved Cotoneaster." The leaves are dark green in color and often turn reddish-purple in the fall, adding to the plant's visual appeal.
3. Flowers: In late spring to early summer, Cotoneaster nummularius produces small, white to pinkish-white flowers in clusters. The flowers are attractive to bees and other pollinators.
4. Fruits: Following the flowers, this cotoneaster develops small, round, bright red berries in the fall. These berries persist through the winter and provide a valuable food source for birds.
5. Garden Uses: Cotoneaster nummularius is commonly used as a ground cover or a low-maintenance shrub in garden borders, rock gardens, and along slopes. Its dense growth habit and attractive foliage make it a popular choice for various landscaping purposes.
6. Growing Conditions: Round-leaved Cotoneaster thrives in well-draining soil and is relatively adaptable to different soil types. It prefers full sun to partial shade and can tolerate a range of climatic conditions.
7. Invasiveness: In some regions, Cotoneaster nummularius has been reported as an invasive species, particularly in North America and parts of Australia. In these areas, it can spread rapidly and outcompete native vegetation.
To prevent potential invasiveness, it's essential to check with local authorities or consult plant experts in your area before introducing Cotoneaster nummularius into your garden or landscape. In regions where it is considered invasive, it is recommended to choose alternative native plant species for landscaping purposes.
