Day jessamine (Cestrum diurnum) is an evergreen shrub with smooth-edged ovate leaves that is native to the West Indies. It blooms fragrant white, trumpet-shaped flowers in stalked clusters which are mildly fragrant during the day and intensifies at night. C. diurnum blooms are followed by 1/4 inch green oval berry fruits which turn a glossy black or eggplant purple as they ripen to shiny blue-black, each containing between 4-14 seeds.

Toxic components
C. diurnum contains calcinogenic glycosides of vitamin D (1,25-dihydroxy vitamin D3). Consumption of calcinogenic glycosides by poultry has resulted in vitamin D intoxication, hypercalcemia, softening of bones, calcinosis, and nephrocalcinosis.
