  • Fun Facts

    This plant goes by a few different common names: andromeda, Japanese andromeda, lily of the valley shrub, and Japanese pieris. Its scientific name, Pieris, derives from the collective name of the muses of Greek mythology. Very fitting for such a beautiful shrub!

  • Long Blooming
  • Winter Interest

Resists: Deer

Maintenance Notes:

Pieris is related to rhododendrons and as such, requires similar conditions: acidic soil, moist but well drained soil, and protection from the worst of winter winds, especially in the colder parts of its range. A 2-3"/5-7cm layer of mulch is very beneficial.

This plant should not be regularly pruned or cut back, but you may selectively remove branches as needed to develop the shape you wish.

Uses Notes:

Pieris makes an outstanding specimen, especially in shaded areas that can be difficult to fill with something truly special. However, with its beautiful evergreen foliage, it lends itself to being planted just about anywhere.
