Cat's Breeches (Hydrophyllum capitatum) is a perennial herb native to the mountainous regions of western North America, including Alberta, British Columbia, Colorado, Idaho, Montana, Oregon, Utah, Washington, and Wyoming. This plant thrives in partial sun or shade, preferring moist conditions with light (sandy), medium, or heavy (clay) soil. Its edible parts—leaves, roots, and shoots—are often used in culinary applications. Cat's Breeches can grow up to 0.5 meters tall and is known for its distinctive white flowers that resemble the legs of a cat, hence its common name. The plant has a moderate pH requirement of 6.4–7.8, making it adaptable to various soil conditions while providing a valuable edible resource in its native range.
