The plant gets its common names from the flowers, which are small, orange and tubular. Each has a white tip with a touch of black, suggesting the ash at the tip of a cigar or cigarette. The leaves are small, elliptical and bright green. A bushy subshrub, it grows up to about 24 in (60 cm) high and benefits from occasional trimming to keep it compact. The species name ignea (also called the specific) is Latin for fire.
