Cestrums come in hundreds of different species, all native to America's tropics. The majority are evergreen and several have strong-smelling flowers that make them appealing ornamental plants. Although several caterpillar species eat cestrums, they should not be consumed by humans as all parts of many of the species are toxic. Cestrums have been known to cause serious losses to livestock in Australia, particularly *Cestrum parqui.*
