Summary

Arctotheca calendula, commonly known as Capeweed, is an evergreen perennial herb native to the coastal plains and disturbed sites in South Africa, including the regions of Lesotho and KwaZulu-Natal. It typically grows to a height of 0.7-1 feet (0.2-0.3 meters) and spreads 1-2 feet (0.3-0.6 meters) wide. Capeweed forms a low-growing mat with hairy stems and daisy-like flowers. The blooms feature a central disc of small yellow florets, sometimes with a green or purple tint, encircled by a halo of larger white or yellow ray petals. The flowering season extends through spring, summer, and fall, with the flowers being moderately showy.

Capeweed is valued for its drought tolerance and ability to form a dense ground cover, making it suitable for erosion control and as an ornamental in xeriscaped gardens. It thrives in full sun and requires minimal water once established, preferring soils with fast drainage. While it can be an attractive groundcover, it has a tendency to become weedy, especially in bare or sparsely vegetated soils. Its invasive potential should be considered before planting, as it can spread both vegetatively and by seed. In regions where it is not native, such as California, it has become invasive, outcompeting local flora and disrupting ecosystems. Gardeners should check local regulations and recommendations before cultivating Arctotheca calendula outside its native range.CC BY-SA 4.0
