Prunus lannesiana, commonly known as Oshima Cherry, is a deciduous tree native to the forest edges and mountain regions of Japan. It typically grows to a height and width of 16-24 feet (5-7 meters), presenting a rounded canopy with a moderate growth rate. The Oshima Cherry is renowned for its abundant and showy white to pale pink flowers that bloom in early spring, creating a spectacular floral display. The bark is smooth and reddish-brown, and the foliage turns yellow to orange in the fall, adding seasonal interest.

The Oshima Cherry is valued for its ornamental flowers and is often used in garden and urban landscapes for its aesthetic appeal. It is suitable for planting as a specimen tree or in small groups. While it prefers full sun, it can tolerate light shade. It requires well-drained soils and is moderately drought-tolerant once established. Gardeners should be aware of potential issues such as cherry leaf spot and aphids, which can affect the health and appearance of the tree. Pruning should be done after flowering to maintain shape and promote healthy growth.CC BY-SA 4.0
