Pieris japonica


 

Pieris japonica
Japanese pieris

Culture: This species performs best in moist, acidic and well-drained organic soils, and should be sheltered from winds and winter sun. It tolerates neutral pH values better than most other Ericaceous plants. It will perform well in full sun if the environment is not too stressful but is preferably grown in partial shade.

In the Eastern U.S., this species has problems with lacebugs that suck sap from the leaves, producing yellow spotted foliage and making culture difficult. If lacebugs are a problem, consider using the native Pieris floribunda. Poor soil drainage may also result in Phytophthora wilt. The lack of winter hardiness, greatly limits the use of this plant in the Midwest to protected locations. Plants in my central Illinois yard vary from 1-4' tall, depending upon the severity of the preceding winter.

Usage: The beautiful white flower displays and the year-round attractive foliage make this a beautiful addition to the landscape where winter temperatures and insects make culture possible. Numerous improved selections exist for the production of heavier flower displays, dwarf sizes, variegated leaves, bright red new foliage and pink flowers. The beauty of many of these cultivars is outstanding. Unfortunately most cultivars are not hardy from central Illinois northward.
