Murraya paniculata, commonly called Mock Orange, is a tropical, evergreen plant bearing small, white, scented flowers, which is grown as an ornamental small tree or shrub. Murraya is closely related to Citrus, and bears small orange to red fruit resembling kumquats, though some cultivars do not set fruit. The plant size is anywhere from 1.5m to 7 m tall and flowers throughout the year. Its leaves are glabrous and glossy, occurring in 3-7 oddly pinnate leaflets which are elliptic to cuneate-obovate to rhombic. Flowers are terminal, corymbose, few-flowered, dense and fragrant. Petals are 12?18 mm long, recurved and white (or fading cream). The fruit of Murraya paniculata is fleshy, oblong-ovoid, coloured red to orange, and grows up to 2.5cm in length.
M. paniculata is a native of South and Southeast Asia, China and Australasia. Traditionally, Murraya paniculata is used both in traditional medicine as an analgesic and for wood (for tool handles). In the West, Murraya paniculata is cultured as an ornamental tree or hedge because of its hardiness, wide range of soil tolerance (M. paniculata may grow in alkaline, clayey, sandy, acidic and loamy soils), and is suitable for larger hedges. The plant flowers throughout the years and produces small, fragrant flower clusters which attract bees, while the fruits attract small frugivorous birds.
Honey Bee farms have been known to plant Mock Orange near bee hives. Serving not only as food for the bees but as protection from harsh winds. Honey collected from bee hive colonies that collect pollen from Mock Orange, have a tangy sweet orange undertone.
M. paniculata is vulnerable to soil nematodes, scales, sooty mold and whiteflies. M. paniculata is the preferred host to the insect pest Diaphorina citri, the citrus psyllid. This psyllid is the vector for the citrus greening disease. The crude ethanolic extract of leaves of Murraya paniculata has antidiarrhoeal, antinociceptive and anti-inflammatory activities. Yuehchukene, a dimeric indole alkaloid, can be extracted from the root.
