Summary

Cicerbita alpina, commonly known as Alpine Sow-Thistle or Alpine Blue-Sow-Thistle, is a perennial herb that is native to the mountainous regions of Europe, including the Alps, Pyrenees, and Carpathians. It typically grows to a height of 20 to 59 inches (50 to 150 centimeters) and features glandular, hairy stems. The leaves of Cicerbita alpina are bluish-grey, contributing to its distinctive appearance, and the plant produces blue-violet, tongue-like florets that bloom from June to September, offering a long-lasting floral display. The flowers are arranged in loose clusters and are quite showy, attracting pollinators such as bees and butterflies.

Alpine Sow-Thistle is valued for its striking flower color and its ability to thrive in cooler, mountainous climates. It is often used in wildflower gardens, rock gardens, and borders in areas that can mimic its native alpine conditions. This plant prefers moist, well-drained soils rich in organic matter and can tolerate partial shade, though it will bloom most prolifically in full sun. While generally low-maintenance, it may require protection from slugs and snails, which find its foliage attractive.CC BY-SA 4.0
