Odontoglossum is a genus of epiphytic orchids that bear ruffled flowers that are generally white but also yellow, brown, or pink. Flowers are borne on erect or arching stalks; a vigorous plant may even produce 2 flower stalks per pseudobulb, usually 12 or more flowers in a raceme.

Odontoglossum needs bright light but not direct sunlight. It wants lots of moisture throughout the year. Odontoglossum blooms best when its roots are crowded. It usually blooms as least twice a year.
