Pedicularis sudetica, commonly known as Sudetic Lousewort, is a perennial herb native to alpine and subalpine meadows, as well as moist, grassy slopes of Northern Europe, Subarctic Asia, and North America. It has also been introduced to parts of North America, including Alaska, Colorado, New Mexico, Wyoming, and Canada. Sudetic Lousewort typically grows to about 1 foot in height and features hermaphroditic flowers that are adapted to its native high-altitude habitats.

This plant is characterized by its fern-like leaves and dense clusters of yellow to pinkish-purple flowers that bloom in the summer. The flowers are tubular and hooded, which are attractive to pollinators such as bees. In cultivation, Sudetic Lousewort is valued for its unique foliage and flowers, which add interest to rock gardens, alpine collections, and naturalized areas. It prefers moist, well-drained soils and can tolerate partial shade, although it thrives in full sun. While not commonly found in cultivation, it can be a conversation piece in a specialized garden setting. Sudetic Lousewort requires consistent moisture and cool conditions to mimic its native alpine environment. It is not known for significant pest or disease problems, but its specialized habitat requirements can make it challenging to grow in lower elevations or warmer climates. There are no widely known cultivars of this species in the horticultural trade.CC BY-SA 4.0
