Tetradium ruticarpum

Rutaceae sp SZ21 clean

Tetradium ruticarpum is a species of flowering plant in the family Rutaceae, native to parts of Asia, including China and Korea. Commonly known as the Korean evodia, bee bee tree, or honey tree, it is valued for its ornamental qualities and its appeal to pollinators such as bees.

Description

Tetradium ruticarpum is a deciduous tree that can grow up to 15-20 meters in height. The leaves are pinnate, typically comprising 5-11 leaflets, each of which is dark green, glossy, and ovate to lanceolate in shape. The tree blooms in late summer, producing clusters of small, fragrant, white flowers. These flowers are hermaphroditic, containing both male and female organs, and are pollinated by bees and other insects. Following the flowering period, the plant produces small, reddish-black fruits which are a source of food for various bird species.

Cultivation and Uses

Tetradium ruticarpum is cultivated as an ornamental tree for its aesthetic appeal and its ability to attract pollinators. It thrives in well-drained soils and prefers full sun to partial shade. The tree is relatively low-maintenance, requiring minimal pruning. It is resistant to most pests and diseases, making it a robust choice for gardens and urban landscapes.

In addition to its ornamental value, Tetradium ruticarpum has been used in traditional Chinese medicine for various purposes, although scientific evidence supporting these uses is limited. The tree's nectar is also highly valued in apiculture, as it produces a rich, high-quality honey.

Ecological Impact

The introduction of Tetradium ruticarpum outside its native range has raised concerns regarding its potential invasiveness. In some regions, it has been reported to spread beyond cultivation and establish in natural areas, potentially displacing native vegetation. However, in its native habitat, it plays a crucial role in supporting biodiversity, offering a valuable food source for pollinators and birds.

Conservation

While Tetradium ruticarpum is not currently listed as endangered, its habitat is threatened by deforestation and urbanization. Conservation efforts are necessary to ensure the preservation of this species and its natural habitat. Sustainable cultivation practices and careful monitoring of its spread in non-native areas are recommended to mitigate potential ecological impacts.
