Myosurus minimus, commonly known as tiny mousetail, is an annual herb that is native to temperate regions of the Northern Hemisphere, including Europe, Asia, North Africa, and North America. It is typically found in moist, open habitats such as wet meadows, marshes, and along riverbanks. The plant forms a small rosette of linear, narrow leaves and reaches a modest height of up to 5 inches (13 centimeters). The most distinctive feature of Myosurus minimus is its inflorescence, which consists of a single flower with an elongated receptacle resembling a mouse’s tail, hence the common name. The flower has curving sepals, five small yellow-green petals, and ten stamens, and it blooms in the spring.

Tiny mousetail is valued for its unique flower structure, which can add interest to moist garden areas or naturalized settings. It is not commonly cultivated but may be of interest to enthusiasts of native and wild plants. In cultivation, it requires consistently moist soil and can tolerate partial shade to full sun conditions. While it is not known for being particularly problematic, its preference for wet conditions means it may not thrive in dry or drought-prone gardens.CC BY-SA 4.0
