About

Cestrum parqui is a medium-sized shrub that can be either deciduous or semi-evergreen, featuring lance-shaped leaves that can grow up to 12 cm long. The plant produces tubular flowers, measuring around 2.5 cm, that are yellow-green and emit a fragrance in the evening. Its fruit is a brownish, oval-shaped berry.

About the genus

Cestrum consists of shrubs or climbing plants that can scramble as they grow. The leaves are simple and remain green year-round. Flowers, which are either tubular or shaped like salvers, appear in clusters at the ends of branches and in the leaf axils, eventually giving way to red or black berries.
