Katsura Pieris (Pieris japonica 'Katsura') is a beautiful evergreen shrub that belongs to the Ericaceae family. The plant is native to eastern Asia and is known for its attractive foliage and showy blooms.

The Katsura Pieris blooms in the early spring, typically in March or April. The flowers are bell-shaped and hang in clusters at the tips of the branches. They are typically white or pale pink in color and have a sweet fragrance that attracts pollinators.

The Katsura Pieris is primarily pollinated by insects such as bees and butterflies. The flowers provide a rich source of nectar and pollen, which is essential for the survival of these pollinators.

The plant is also capable of self-pollination. However, cross-pollination between different individuals is beneficial for the genetic diversity of the species.

The Katsura Pieris is not self-fertile and requires the transfer of pollen from another plant to produce viable seeds. Seed production is not a common occurrence in ornamental plants like the Katsura Pieris.

Overall, the Katsura Pieris is a beautiful and valuable addition to any landscape. Its attractive flowers and foliage provide year-round interest, and it supports local pollinators.

Katsura Pieris (Pieris japonica 'Katsura') FAQ

What is Katsura Pieris?

Katsura Pieris, also known as Pieris japonica 'Katsura', is a broadleaf evergreen shrub that belongs to the Ericaceae family. It's native to the forests of Japan, Taiwan, and eastern China. Katsura Pieris is prized for its elegant foliage and showy, fragrant flowers. It's ideal for use as a specimen plant, border, woodland garden, or foundation planting.

What are the characteristics of Katsura Pieris?

Katsura Pieris typically grows to a height and spread of 6-10 feet. It has oval, glossy, dark green leaves that are 2-4 inches long. In late winter or early spring, it produces drooping clusters of bell-shaped, pinkish-white flowers that are 4-8 inches long. The flowers have a sweet fragrance and attract pollinators such as bees, butterflies, and hummingbirds. After flowering, Katsura Pieris produces seed capsules that turn brown and persist into the fall. The plant prefers acidic soil and partial shade but can tolerate full sun in cool, moist climates.

How do I plant Katsura Pieris?

Katsura Pieris is best planted in spring or fall when the soil is moist and cool. Choose a site with well-draining, acidic soil (pH 4.5-6.0) that is rich in organic matter. Dig a hole that's slightly larger than the root ball and plant the shrub at the same depth as it was in the container. Water thoroughly and mulch around the base of the plant to conserve moisture and suppress weeds. Keep the soil consistently moist but not waterlogged, especially during the first year of establishment.

How do I care for Katsura Pieris?

Katsura Pieris is low-maintenance and generally pest and disease-free. However, it may be susceptible to root rot, leaf spot, and lacebugs in poorly drained soil or humid conditions. To care for Katsura Pieris:

• Fertilize in early spring with an acidic fertilizer
• Prune after flowering to maintain shape and remove dead or damaged branches
• Water deeply and regularly during dry spells
• Avoid overhead watering to prevent waterlogging the leaves
• Cover plants with burlap in winter to protect from frost damage

Can Katsura Pieris be propagated?

Yes, Katsura Pieris can be propagated by seed, cuttings, or layering. Seed should be sown in a well-draining, acidic soil mix in early spring and covered with a thin layer of sand or vermiculite. Cuttings should be taken in early summer and propagated in a rooting hormone and sandy soil mixture. Layering involves bending a low branch to the ground and covering the section with soil, allowing roots to form before separating from the parent plant.

What are the cultivars of Pieris japonica?

Pieris japonica has several cultivars, including:

• 'Katsura': Pinkish-white flowers and bronze-red new leaves
• 'Valley Valentine': Deep red flowers and dark green leaves
• 'Mountain Fire': Red new growth and white flowers
