Japanese Pieris (Pieris Japonica ‘Shojo’)

Japanese Pieris

Features and Characteristics

Pieris japonica is a broadleaf evergreen shrub that typically matures to 9-12’ tall with a dense, upright habit. It features drooping clusters (racemes to 6” long) of lily-of-the-valley-like white flowers in early spring. Serrulate, oblanceolate to obovate-oblong leaves (to 5” long) emerge orange-bronze but mature to glossy dark green. Leaves are evergreen. Bead-like flower buds are set in late summer for the following year and provide winter interest and contrast to the evergreen foliage. Many cultivars are available featuring flowers in various shades of white, pink and deep rose.

Synonymous with and sometimes sold as Andromeda japonica.

Genus name is the name of one of the Greek Muses.

Specific epithet means of Japan.

‘Shojo’ is a compact, mounded, evergreen shrub that is smaller than the species. Its new foliage is a soft red maturing to a deep green. The deep pink, bell-shaped flowers of ‘Shojo’ emerge from dark red-black buds in early spring. ‘Shojo’ grows 3 to 6 ft. tall and wide.

Care and Maintenance

Best grown in organically rich, slightly acidic, medium moisture, well-drained soil in full sun to part shade. In St. Louis, Japanese pieris doesn’t seem to perform well in most locations. Summer foliage decline and reduced vigor results in weakened plants that may succumb to a harsh winter. It grows best in locations sheltered from wind with some afternoon shade. Remove spent flowers immediately after bloom.
