, a South American species, has become established in coastal regions of south and central California, probably due to spreading from cultivated specimens. Both flowers and leaves are large; the round leaves are about 4 inches in diameter, attached in the center to a long stalk (peltate), and forming a dense mat covering the ground for several square feet. Flowers are colored various shades of orange, red and yellow - either a single color or bilcolored - and measure 2 inches across; they are formed of five rounded petals of which the lower three have inwards-pointing claws near the base, while the upper two have dark veins radiating from the base. In the center are eight short stamens. A thin, tapering nectar spur extends down beneath the flower head.
