Cotula
Also called Water Buttons, Brass Buttons, Buttonweeds, Buttons, Goosegrasses, Bachelors' Buttons
Cotula is a genus of small, low-growing daisy-family plants, often called water buttons or buttonweeds, with tiny button-like flower heads. Commonly grown members, such as Cotula coronopifolia (brass buttons), are used as tough, low ground cover that tolerates foot traffic.
Cotula is a genus of flowering plant in the sunflower family. It includes plants known generally as water buttons or buttonweeds.
The species within this genus can vary extensively in their habit, leaf division, involucre, receptacle and achenes. This makes it difficult to define them by comparing their morphology. The genus can only be defined by looking at the corollas of their flowers. Most are disciform (lacking ray florets). These corollas may be tubular, reduced or even absent. Another characteristic is their solitary heads growing on a peduncle.
Cotula is used in New Zealand as ground cover for bowling greens, playing fields on which the ball-game of bowls is played.
