Description Description Cotula coronopifolia is a perennial or annual herb. Leaves are alternate, either entire to apically trifid or regularly pinnate to bipinnate found in the Namaqualand populations.

The leaf base is dilated which forms a prominent sheath around the stem; leaf sheath is between 4. Bracts has either 1 or 2 series; bracts are oblong to lanceolate. Flowerhead consists of 2 types of florets: a single series of female disciforms and inner series of yellow disc florets ca. Conservation Status Status Cotula coronopifolia is a common widespread species and there is no threat to cause this species to go extinct. As a result, this species is listed as Least Concern LC.

Distribution and habitat Distribution description Cotula coronopifolia is found to be widespread in the Eastern, Northern and Western Cape. The species is also naturalized in isolated populations in Gauteng and in other parts of the world, such as North America, South America, Europe and Australia.

Flowering time is mainly May to October late autumn to spring. It has also been noted that dispersal can be carried out by birds, but this type of dispersal is highly unlikely and if it does occur, it is rare.

Horticulturally it is used as a decorative plant around a body of water, such as a pond. In Europe they are found to be in freshwater ponds in the cities. Growing Cotula coronopifolia Grow Cotula coronopifolia can be propagated fairly easily from either seeds or cuttings and do not need any prior treatment. If propagating from a cutting, the cutting selected should be a piece of the stem that has roots occurring at the nodes.

If smaller individuals of the species are desired, then waterlogged soil is ideal. They grow in full sun but can tolerate partial shade. This species can be used as a garden plant as a feature next to a pond or water feature where the numerous bright yellow flowerheads will be a lovely contrast to the green colour of the leaves.

This combination will be a stunning addition to any garden. Cotula coronopifolia has no known pests or diseases. References Lovas-Kiss, A.
