Cotula lineariloba, commonly known as Big Yellow Moon, is an evergreen perennial herb native to the grassy slopes and open areas of South Africa, particularly in regions such as Lesotho and KwaZulu-Natal. It typically grows to a height and width of approximately 5 feet (1.5 meters), forming a dense, mounded clump. Big Yellow Moon is characterized by its fine, linear leaves and bright yellow, daisy-like flowers that bloom in spring, providing a showy display that can add a splash of color to any garden setting.

This plant is valued for its vibrant yellow blooms and its ability to thrive with minimal care, making it a popular choice for rock gardens, borders, and as ground cover in warm climates. It is drought-tolerant once established, which makes it suitable for xeriscaping. In cultivation, Big Yellow Moon prefers full sun exposure and can tolerate a range of soil types, provided they have good drainage. While it is generally low-maintenance, it can be susceptible to root rot if overwatered or planted in poorly drained soils. It is not known to have aggressive roots or significant disease problems, but it should be monitored for common pests such as aphids.CC BY-SA 4.0
