Murraya paniculata
The common jasmin orange is a native plant of Taiwan, widely distributed throughout the tropical regions of Asia and is commonly cultivated artificially. The species was initially planted in the Coral Atoll Area and the Taitung Cycad Area of the Botanical Garden. At present, natural regeneration is evident, with seedlings occurring throughout the entire garden. Furthermore, a hedgerow has been established along Xitun Road, adjacent to the security room.
It is an evergreen shrub or small tree with small, glossy leaves that emit a citrus scent when rubbed. The small white flowers have five petals and emit a strong fragrance that can be detected from hundreds of meters away, hence it has the nickname “seven-kilometer fragrance” in Taiwan. The fruit turns bright red when ripe and resembles a lemon in shape but is less than 1.5 centimeters in diameter.
The tree has a compact and elegant form, with numerous branches that are tolerant of pruning. It is often used as a hedge plant to create garden landscape or as a decorative barrier in public spaces. The growth rate of its branches and leaves is relatively slow, resulting in a stable tree form that is resistant to deformation and easy to maintain in a neat and attractive condition. As a result, it is also regarded as a premium bonsai species or material for green sculptures, and is highly favored by gardening enthusiasts. It has strong adaptability to the environment, with low requirements for soil and climate conditions, and good drought tolerance, enabling it to thrive in various environments. Therefore it holds significant application value in greening projects. Ecologically, the branches and leaves of the common jasmin orange provide habitats for insects, while its flowers and fruits serve as food sources, contributing to the maintenance of ecological balance.
In addition to its use in horticultural landscaping, the wood of the common jasmin orange has delicate and hard texture, so it is suitable for making seals. The flowers have high nectar and pollen yields, making them good honey plants.
