The tender species require a compost of loam, leafmould, and a little sand and should be planted singly in 5-6 inch pots placed in a sunny position. Water freely during the summer and feed regularly with a liquid fertilizer. Pot up or plant in early spring. Propagate hardy species by division every three years, and greenhouse species from seed sown in sandy soil in heat in the spring or from cuttings placed in sandy soil in heat between January and April. P. alkekengi grows very vigorously and spreads by means of underground runners. It may be used as a deciduous ground cover plant in sun or semi-shade.
