Ask the Expert: What kind of Orchid do I have? I bought this orchid in Key West 3 years ago. It keeps growing new psuedobulbs and flowers this time of year. I am just very curious what classification of orchid it is so I can better care for it and ask advice. Thanks Yellow Blooms Plant Expert Reply: It looks like an Oncidium. Depending on which species of Oncidium you have the orchid will need any where from bright to nearly full direct sun. They need 30 to 60% humidity and 80 to 85 degree day temps with 55 to 60 at night. Water thoroughly, but allow the medium to dry half way between waterings.
