Brassavola nodosa is a small, tough species of orchid native to Mexico, the West Indies, Venezuela and Peru. It is also known as "Lady of the Night" orchid due to its citrus and gardenia-like fragrance which begins in the early evening. Its fragrance and whiteish-green color combine to attract night-pollinating moths.

The diploid chromosome number of B. nodosa has been determined to be 2n = 40
