Wyethia amplexicaulis, commonly known as Mule-Ears, is a deciduous perennial herb native to open woodlands, meadows, and dry slopes in the Western United States, particularly in the Rocky Mountains and the Sierra Nevada. It typically grows to a height of 3 feet (0.9 meters) and a width of 1-2 feet (0.3-0.6 meters). Mule-Ears is characterized by its large, basal leaves that resemble the ears of a mule, and its showy, bright yellow, sunflower-like flowers that bloom in late spring to early summer. The plant’s appearance adds a splash of color to wildflower meadows and naturalistic garden settings.

Mule-Ears is valued for its ease of maintenance and drought tolerance once established, making it suitable for xeriscaping and native plant gardens. It is often used in restoration projects and as an ornamental in dry, sunny borders. This plant prefers full sun exposure and thrives in well-drained soils, though it can tolerate a range of soil types. While generally pest-free, it can be susceptible to root rot if overwatered. Mule-Ears is not known for aggressive roots or significant disease problems, but it can be difficult to transplant due to its taproot system.CC BY-SA 4.0
