番茉莉屬常綠或半落葉灌木，原產巴西。互生長橢圓形或倒卵形葉。花單生或簇生於枝端及葉腋；花初開時紫色，漸褪為淺紫，最終變為白色後凋謝。花具有濃郁芳香味。在臺灣栽培罕見結果。開花期春至秋季，3與10月開花最盛。

An evergreen or semi-deciduous shrub in the genus Brunfelsia, native to Brazil. Leaves alternate, oval or obovate. Flowers solitary or clustered on the branch tips and leaf axils; flowers purple initially, then fading and wilting in white eventually; richly aromatic. Rarely fruiting for cultivars in Taiwan. Flowering from spring to autumn, full bloom in March and October.

半日照或全日環境。於夏季烈陽曝曬處種植葉片容易呈黃綠色，會減損觀賞價值。水分須充足供應，缺水容易生長不良甚至造成落葉。冬季可進行強剪以更新樹勢並讓來春開花繁茂。繁殖使用扦插、空中壓條法。

The plant grows in partial sun or full sun environments. The leaves easily turn yellow-green if exposing to sun in summer which reduces the ornamental value. Regular water use is required as lacking of water can result in poor growth and even defoliation. Hard pruning is suitably performed in winter to reactivate the growth and boost the bloom in the following spring. Propagated by cuttings and air layering.

花朵氣味接近茉莉花香而得名，花香於雨後或傍晚溼度高時尤其馥郁。適合種植於疏樹蔭下或牆邊、中庭等陽光不過度曝曬處。單株、多株叢植或列植為綠籬皆可。全株有毒，花朵不能食用。

The flowers smell like jasmine which gives rise to the Chinese common name. The floral fragrance gets richer especially after raining or when the humidity is high in the evening. Suitably planted in shades under sparse trees, along walls, atriums and other places without excessive sun exposure; planted alone, in clusters, or in rows as hedges. The whole plant is poisonous and the flowers are also inedible.
