This large family of orchids has varied growing needs. Many
come in yellows, browns, and pinks.
- All need bright light, but some may need full sun.
- Some need intermediate temperatures, while others need to
be kept warmer. Tolumnias, Oncidium relatives from the Caribbean, need warm temperatures.
- Typically, Oncidiums with thin leaves need frequent water.
Those with thick leaves or pseudobulbs can dry out between waterings,
and need a winter dormancy.
- Repot every 2-3 years.
Oncidiums can be crossbred with closely related orchids to create
hybrids. Hybrid plants combine the best qualities of both parents, and
some can survive poor growing conditions or neglect. This
"hybrid durability" makes them great choices for beginning orchid
growers. Oncidium hybrids include:
Brassia x Cochlioda x Miltonia x Odontoglossum, abbreviated
Miltonia x Odontoglossum x Oncidium, abbreviated Colm.
Brassia x Odontoglossum x Oncidium,
Cochlioda x Odontoglossum, abbreviated Oda.
Odontoglossum x Oncidium, abbreviated Odcdm.
Odontoglossum x Miltonia, abbreviated Odtna.
Cochlioda x Miltonia x Odontoglossum, abbreviated Vuyl.
Cochlioda x Odontoglossum x Oncidium, abbreviated Wils.
