Styphnolobium japonicum aka Japanese Pagoda Tree

Taxonomy

Styphnolobium japonicum, commonly known as the Japanese pagoda tree or Chinese scholar tree, is a species of tree in the pea family Fabaceae. It was previously classified under the genus Sophora but is now recognized as a separate species. Unlike Sophora, Styphnolobium does not have the ability to form symbiotic relationships with nitrogen-fixing bacteria on its roots. It is also distinct from the related genus Calia in having deciduous leaves and flowers that grow in axillary racemes rather than terminal ones. The tree can reach heights of up to 25m and has a rounded, low-branched shape. Its pinnate leaves are rich green and can grow up to 30cm in length. Fragrant, creamy-white, pea-shaped flowers measuring 12mm in length are produced in terminal panicles on mature trees. Native to China and Korea, the Japanese pagoda tree is cultivated for its attractive compound foliage and fragrant late summer flowers. The leaves, composed of 7-17 oval, dark green leaflets, remain vibrant throughout the growing season. Although it is not native to Japan, the tree has historical significance in Japanese Buddhist temples, which is reflected in its specific epithet and common name. The tree's flowers give way to slender, brown pods that contain one to six seeds and persist into winter.

How to care for Japanese Pagoda Tree

Difficulty

With a bit of knowledge and dedication, you can successfully care for Japanese Pagoda Tree, making it a rewarding choice for those seeking a moderate challenge.

Water

Japanese Pagoda Tree should be watered regularly, allowing the soil to dry out between waterings.

Soil

Japanese Pagoda Tree loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

Japanese Pagoda Tree requires abundant, bright, and direct light to thrive. The best placement for this plant is within one foot of a window to ensure it receives enough light. If you live in an area with more extreme weather, such as hot summers or cold winters, you may need to adjust the placement of the plant accordingly. During hot summer months, it is important to place the plant away from full sun, as this can cause the leaves to yellow or burn. During cold winter months, it is best to move the plant closer to the window to take advantage of the extra light that can help it survive. By keeping an eye on the current weather in your area, you can make sure your Pagoda Tree is always in the right place to thrive.

Toxicity

No verified data on the toxicity of this plant exists within Ploi's records. Should you, someone in your family, or your pet ingest plant material with an unknown toxicity level, it is recommended to seek medical advice.
