Arctotheca calendula is a plant in the sunflower family commonly known as capeweed, plain treasureflower, cape dandelion, or cape marigold because it originates from the Cape Province in South Africa. It is also found in neighboring KwaZulu-Natal. Description Arctotheca calendula is a squat perennial or annual which grows in rosettes and sends out stolons and can spread across the ground quickly. The leaves are covered with white woolly hairs, especially on their undersides. The leaves are lobed or deeply toothed. Hairy stems bear daisy-like flowers with small yellow petals that sometimes have a green or purple tint surrounded by white or yellow ray petals extending further out from the flower centers. Cultivation It is cultivated as an attractive ornamental groundcover but has invasive potential when introduced to a new area. The plant can reproduce vegetatively or via seed. Seed-bearing plants are most likely to become weedy, taking hold most easily in bare or sparsely vegetated soil or disturbed areas. Spread Arctotheca calendula is naturalized in California, Spain, Portugal, Italy, Australia, and New Zealand, and considered a noxious weed in some of those places.
