Ada aurantiaca is an epiphytic orchid from the genus Ada.


Plants bloom between January and April in culture. Inflorescences bear 5 to 10 brilliantly orange colored flowers.


No natural hybrid has been described.

First articifial hybrids were Adaglossum Juno (x Odontoglossum edwardii) and Adioda St. Fuscien(x Cochliodoa densiflora), both registered in 1913.

In intergeneric breeding, Ada aurantiaca received attention due to it's intense, deep orange colored flowers. Ada aurantiaca was most often crossed to Brassia (=Brassada), Odontoglossum (=Adaglossum), and Odontioda (=Stewartara). Some more complex hybrids have been generated like Hamiltonara (x Brassia x Odontoglossum x Cochlioda), Banfieldara (x Brassia x Odontoglossum), and Kriegerara (x Cochlioda x Odontoglossum x Oncidium).


Plants are found in northwestern Venezuela, Columbia and Ecuador, growing epiphytically in cloud forests of the higher mountain regions, at elevations between 2,300 and 2,500 meters. In the natural habitat, plants are exposed to humid conditions, and cool temperatures.


Grow in cool conditions with moderate light during Summer, and more light during Winter. During the growing period, high humidity is essential for successful cultivation. The pot medium should not dry out completely when growing, but sufficient drainage is needed to avoid root rot. At all time mist the plants frequently, if possibly in the morning to mimic the morning dew of the natural habitat. Plants should be potted in a well drain medium such as medium fir bark. High temparatures in Summer can easily destroy a plant, but if given the cool conditions it needs, it is an easy grower.
