The Colorful Little Heath Japanese Pieris
This small evergreen shrub is great for containers and small yards.
Little Heath Japanese Pieris (Pieris japonica ‘Little Heath’) is a cultivar of Japanese Andromeda, a slow-growing evergreen shrub native to Japan, Taiwan, and eastern China. It is a member of the heather (Ericaceae) family, which also includes rhododendrons and azaleas. Pieris is grown for its attractive foliage and pendulous clusters of bell-shaped, lightly scented spring flowers, which can last up to three weeks long in zones 5-8.
Little Heath Japanese Pieris was selected for its colorful foliage and small size. Leaves emerge in spring in shades of pink and red, fading to variegated cream and green as the season progresses. Pink buds open to reveal clusters of white flowers, a favorite source of early spring nectar for mason bees. Little Heath Japanese Pieris is a dwarf cultivar, growing slowly to a mature size of 2-3 feet tall and wide, making it suitable for containers and small gardens.
Little Heath Japanese Pieris has specific cultural requirements, which give it the reputation of being somewhat fussy to grow. It requires moist, well-draining, acidic soil that is rich in organic matter, and grows best in full sun to partial shade with protection from hot afternoon sun and drying winds.
Plant Little Heath Japanese Pieris along side other acid-loving, partial-shade seekers like Japanese camellias, hollies, rhododendrons and azaleas. As with any other shrub, water deeply on a regular basis until the plant becomes established (see “How to Water your Plants” for help coming up with a watering schedule).
Little Heath Japanese Pieris is one of the most deer-resistant shrubs or bushes you can plant. Pieris japonica is given top marks for deer resistance by Rutgers University on their list of Landscape Plants Rated by Deer Resistance. Deer don’t like the taste of the foliage, and tend to leave it alone. However, no plant is 100% deer resistant, and deer will eat anything when their favorite foods are scarce.
It's worth noting that while Little Heath Japanese Pieris is a beautiful and popular ornamental plant, parts of it can be toxic if ingested, so it's important to be cautious, especially if you have pets or small children.
In spring, the fresh new leaves of Little Heath Japanese Pieris unfurl in shades of pink and red.
