[4] The name of the genus refers to the epiphytic growth habit of the species,[5] and literally means "air-plant".

The species in this genus range from small to large monopodial epiphytes, except for Aerides krabiensis, which is a lithophyte.

[4] They form pendulous racemes with many long-lasting, fragrant, waxy flowers, which are often white with purple or pink edges.

[4] Aerides can be kept in hanging baskets, teak containers or net pots, which allow the roots to extend into the air.

They grow best in well-drained media, such as tree fern fibers, fir bark, and sphagnum moss.

Hybrids come in a wide range of colors due to the high degree of genetic diversity.
