Rock's tree peony

Best grown in neutral, humus rich soils, but slightly acid or slightly alkaline soils are tolerated. Good drainage is essential. Ideally, plant in a sunny position. Can be grown in light shade, but the plants may become straggly. Fully hardy, but young foliage and flowers can be damaged by late frost. See tree peony cultivation for further information.
