Prunus × subhirtella, commonly known as the Winter-flowering Cherry, Higan Cherry, or Spring Cherry, is a hybrid species of cherry tree in the genus Prunus. It is widely appreciated for its aesthetic appeal and is often planted in gardens and parks for its decorative flowers. The tree is a hybrid between Prunus speciosa (Oshima cherry) and Prunus incisa (Fuji cherry), showcasing characteristics from both parent species.

Description[edit | edit source]

Prunus × subhirtella is a deciduous tree that can grow to a height of 15–25 feet. It has a spreading habit, with branches that can create a rounded canopy. The leaves are simple, ovate to lanceolate in shape, measuring 2–5 inches in length, with serrate margins. In autumn, the foliage turns to vibrant shades of yellow, orange, or red, adding seasonal interest.

The tree is best known for its flowers, which appear in early spring or sometimes during mild winters. The flowers are typically pale pink to white, about 0.5 inches in diameter, and bloom in clusters before the leaves emerge. Some cultivars may have double flowers or vary in color intensity.

Cultivation[edit | edit source]

Prunus × subhirtella prefers well-drained, fertile soil and can be planted in full sun to partial shade. It is relatively low maintenance but may require pruning to maintain its shape and remove any dead or diseased wood. The tree is hardy in USDA zones 5 through 8, making it suitable for a wide range of climates.

Cultivars[edit | edit source]

Several cultivars of Prunus × subhirtella have been developed, each with unique characteristics. Some of the most popular include:

  • Prunus × subhirtella 'Autumnalis' - Noted for its ability to flower sporadically during mild winter periods as well as in spring.
  • Prunus × subhirtella 'Pendula' - A weeping form that is often used as a focal point in landscapes.
  • Prunus × subhirtella 'Rosea' - Similar to 'Autumnalis' but with pinker flowers.

Uses[edit | edit source]

Prunus × subhirtella is primarily used for ornamental purposes. It is a popular choice for residential gardens, public parks, and streetscapes. The tree's compact size makes it suitable for small gardens, and its seasonal changes provide year-round interest. Additionally, it is sometimes used in bonsai cultivation.

Conservation[edit | edit source]

While Prunus × subhirtella is not considered endangered, it is subject to the same threats as other cherry species, including pests and diseases such as cherry leaf spot, powdery mildew, and aphids. Proper care and monitoring can help maintain healthy trees.
