What is the family name for orchids?

The family name for orchids is Orchidaceae. It is a major family of flowering plants in the order Asparagales and includes the plants commonly called orchids, from tropical epiphytes to terrestrial species in temperate regions.

Orchidaceae is exceptionally diverse. Its members occur on every continent except Antarctica, with especially rich diversity in tropical and subtropical regions. Many orchids grow on trees as epiphytes, using them for support rather than taking nutrients from them. Others grow in soil or on rocks. Their flowers often have highly specialized shapes, scents, colors, and pollination mechanisms.

The name comes from Orchis, the type genus, whose paired underground tubers were thought to resemble testicles. A frequent classification mistake is treating Orchidaceae as a genus: it is a family, while genera such as Orchis, Vanilla, and Phalaenopsis sit inside it. Orchid seeds are famously tiny and often depend on fungal partners to germinate, an unusual life-history feature that helps explain why orchid biology is so distinctive.
