The plant features finely divided, pinnate leaves with slender, linear segments, giving it a delicate, fern-like appearance. The flowers are small, 1-2 cm (0.4-0.8 inches) in diameter, and are usually yellow or orange with a single or double layer of petals. The flowers have a distinctive citrus-like fragrance.
