Arctostaphylos uva-ursi
Arctostaphylos uva-ursi, commonly known as Kinnikinnick or Bearberry, is favored for its hardiness and aesthetic appeal; this low-growing evergreen brings beauty and versatility to gardens. Explore its native range, hardiness, detailed propagation methods, ideal growth conditions, and remarkable cultivars.
Native Range and Habitat
Kinnikinnick naturally occurs in the cooler regions of North America, Europe, and Asia. It thrives in various habitats, including coastal beaches and mountainous areas, showcasing its adaptability.
Plant Description and Hardiness
This evergreen shrub usually remains under 6 inches in height but can spread significantly. Its small, leathery leaves stay green year-round, complemented by bell-shaped flowers in the spring and red berries in the fall and winter. Kinnikinnick is hardy in USDA zones 2 through 6 and can withstand poor soil conditions and harsh environments.
Propagation Methods
Kinnikinnick can be propagated through seeds and cuttings. For nursery production, cuttings are preferred to maintain genetic consistency. Semi-hardwood cuttings taken in late summer are particularly effective for propagation, ensuring healthier and uniform plants.
Growth Conditions
Soil: Kinnikinnick prefers well-drained, sandy, or rocky soils with a slightly acidic to neutral pH.
Light: It thrives best in full sun to partial shade.
Water: Drought-tolerant once established, Kinnikinnick requires regular watering during its initial growth phase to ensure a strong start.
Pest Control: While generally resistant to pests and diseases, it can be susceptible to leaf spot and root rot in poorly drained soils. Good cultural practices and proper soil drainage are vital to preventing these issues.
