Erythranthe moschata, commonly known as muskflower or musk monkeyflower, is a rhizomatous perennial herb that is native to moist habitats such as stream banks, wet meadows, and seeps in western North America, from British Columbia through California and eastward to the Rocky Mountains. It has also naturalized in parts of eastern North America, Chile, and Europe. The plant typically has prostrate or upright stems that can reach up to 12 inches in length, and it bears yellow, tubular flowers that are mildly showy. The foliage was once noted for its musky fragrance, which has been absent in both wild and cultivated plants since around 1913.

Musk monkeyflower is valued for its ability to thrive in wet conditions and is often used in water gardens, bog gardens, and around ponds. It prefers partial shade but can tolerate full sun in cooler climates, provided it has ample moisture. The plant requires soils with good moisture retention and does not tolerate drought well. While it is not commonly grown for its scent anymore, it remains a charming addition to naturalistic plantings and can provide a naturalistic aesthetic to garden spaces. It is relatively low-maintenance but can be susceptible to powdery mildew and should be monitored for this disease.CC BY-SA 4.0
