Quercus phillyraeoides, or Ubame oak, has glossy, leathery, evergreen leaves with finely serrated edges, providing year-round greenery and shade

Quercus phillyraeoides, commonly known as Ubame oak, is an evergreen tree native to East Asia, specifically Japan, Korea, and southern China. It's a species that has garnered attention for its unique characteristics, including its distinctive leaves.

The leaves of Quercus phillyraeoides are a testament to the oak's adaptability. They are typically elliptic or ovate in shape, with a glossy, leathery texture that reflects their evergreen nature. This texture is an adaptation to drier conditions, helping to reduce water loss. The leaf margins are often finely serrated, giving them a delicate appearance. Unlike many other oak species, Ubame oak retains its leaves throughout the year, providing consistent greenery in landscapes.

The leaves are typically medium-sized and arranged alternately on the branches. Their dark green color creates a dense canopy that provides shade during the warmer months. While the leaves don't exhibit the vibrant autumnal hues of deciduous oaks, they offer a constant, rich green backdrop throughout the year. This evergreen characteristic, combined with the tree's relatively compact size, makes it a popular choice for landscaping and bonsai cultivation.

Beyond their aesthetic appeal, the leaves of Quercus phillyraeoides play a crucial role in the tree's ecology. They contribute to the formation of leaf litter, which enriches the soil and supports a diverse ecosystem. Additionally, the tree's evergreen nature provides shelter and food for various wildlife species throughout the year.
