--><p>Some species of Cestrum are cultivated as ornamentals in warmer parts of the United States. Three are established in the flora area, and C. aurantiacum Lindley and C. fasciculatum (Schlechtendal) Miers may become established; they are shrubs or trees (to 4–5 m) and have brightly colored corollas (orange in C. aurantiacum and pink or red in C. fasciculatum). Berries of C. aurantiacum are white; those of C. fasciculatum are red. Cestrum fasciculatum may also be known as C. elegans Francey, an illegitimate homonym.</p>
