Campanula lasiocarpa, commonly known as Mountain Harebell or Alaska Harebell, is a perennial herb that thrives in the alpine and subalpine zones of northwestern North America, including Alaska, Washington, Alberta, British Columbia, the Northwest Territories, and the Yukon. It is typically found in meadows, rocky slopes, and tundra environments, where it contributes to the biodiversity of these high-elevation ecosystems. The plant reaches a modest height of 5-10 inches (13-25 cm) and spreads 6-12 inches (15-30 cm) wide. Its appearance is characterized by a clumping form with lance-shaped leaves and striking blue, bell-shaped flowers that bloom from late spring to early summer. The flowers are particularly showy, attracting pollinators such as bees and butterflies.

Mountain Harebell is valued for its cold hardiness and ability to thrive in rocky, well-drained soils, making it an excellent choice for alpine gardens, rockeries, and as a ground cover in cold, mountainous regions. It requires minimal maintenance once established and is relatively drought-tolerant, although it appreciates consistent moisture. In cultivation, it prefers full sun to partial shade and can adapt to a variety of soil types, provided they are well-draining. There are no major disease or pest issues, but it can be susceptible to root rot in poorly drained soils. This plant is not known to be invasive and does not have aggressive roots, making it a safe choice for most garden settings.CC BY-SA 4.0
