It is a evergreen shrub that is a hybrid between the "Sage-leaved rockrose" (Cistus salviifolius), which is found in southern Europe, parts of western Asia, and North Africa, and "Poplar-leaved cistus" (Cistus populifolius), which is found from Portugal to northern Spain and France. It grows in a bushy form and is 60 to 150 cm tall. The leaves are ovate to cordate, opposite, with wavy margins. It produces white flowers, 3.5 cm in diameter, from June to July. There are five petals with a yellow spot at the base.
