are tomatoes a member of the nightshade family
Solanaceae The Solanaceae, or nightshades, are an economically important family of flowering plants. The family ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of important agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many, including tomatoes, potatoes, eggplant, bell/chili peppers, and tobacco are widely used. The family belongs to the order Solanales, in the asterid group and class Magnoliopsida (dicotyledons).[2] The Solanaceae consists of about 98 genera and some 2,700 species,[3] with a great diversity of habitats, morphology and ecology.
Night-blooming cereus Night-blooming cereus is the common name referring to a large number of flowering ceroid cacti that bloom at night. The flowers are short lived, and some of these species, such as Selenicereus grandiflorus, bloom only once a year, for a single night.[1] Other names for one or more cacti with this habit are princess of the night, Honolulu queen (for Hylocereus undatus), Christ in the manger, dama de noche and queen of the night (which is also used for an unrelated plant species).
