Group : Twig_epiphyte
Covers these genera : Barbosella (Bar.) , Cischweinfia (Cisch.) , Fernandezia (Frnndz.) , Lepanthes (Lths.) , Lockhartia (Lhta.) , Mediocalcar (Medi.) , Oberonia (Obrnia.) , Ornithocephalus (Orcp.) , Porroglossum (Prgm.) , Psygmorchis (Psgmrc.) , Sigmatostalix (Sgmx.) , Telipogon (Tp.) , Zelenkoa (Zel.)

General information for this group :
Most members of this group require nearly identical conditions. They are easy to grow and bloom when provided with the right environment. Many adorable miniatures are included in this group. The technical term "twig-epiphyte" refers to plants that grow on small twigs only, and typically in cloud-forests. In that habitat the branches are covered in moss and lichens, and are constantly drenched in dew from condensation. We are broadening this definition to include plants coming from different habitats, possibly with less humidity than available in cloud-forests. Most of these plants are micro-minis as mature plants. Under the right conditions they spread quickly forming mats or clumps. The initial discussion is for Twig-epiphytes that prefer intermediate temperatures. For subgroups that have additional information, it will appear under individual headings near the bottom of the page. Alternatively, you can click on the genus name above to take you directly to that subgroup.

Subgroup : Intermediate Growers

Covers these genera : Barbosella (Bar.) , Cischweinfia (Cisch.) , Lockhartia (Lhta.) , Mediocalcar (Medi.) , Oberonia (Obrnia.) , Ornithocephalus (Orcp.) , Psygmorchis (Psgmrc.) , Sigmatostalix (Sgmx.) , Zelenkoa (Zel.)

Description :
Lockhartia is likely the largest member of this group, with the balance usually remaining very diminutive. Most are quite floriferous provided the right growing conditions.

Light :
Most prefer moderate to low light, which typically provides more of the humidity that they crave. These do well under fluorescents, in terrariums, or under the leaves of larger plants.

When in doubt about growing conditions, research the native habitat of the plant in question for more information.

Temperature :
Intermediate temperatures suit most of these best. If warmer temperatures occur, then increasing the humidity will help to compensate to avoid excessive stress on the plants.

Media :
Best grown mounted on tree-fern or cork, with minimal or no sphagnum padding.

Water :
Water must be high-quality as in rainwater or dehumidifier water. Do NOT even think about using tap-water, well-water or bottled water, with the worst choice being softened water. The wrong water will often result in a death-spiral, even if only used once !

Fertilizing :
Use only a balanced orchid fertilizer (3:1:3 or 4:1:4 ratio), and never greater than 1/4 strength. Fertilize only during active growth, flushing completely every 3rd watering. If you are growing under lights or in a terrarium, you can fertilize year-round. On windowsills however, only fertilize from February through September. These plants are light feeders.

Blooming :
Blooming usually occurs throughout the year, with the greatest flush in late spring.

Subgroup : Cool Growers

Covers these genera : Fernandezia (Frnndz.) , Lepanthes (Lths.) , Porroglossum (Prgm.) , Telipogon (Tp.)

Description :

Same as for Intermediate Growers, except :

  • Fernandezia and Telipogon will NOT tolerate warmer temperatures, and must be kept cool or even cold in some cases.
  • This subgroup will not tolerate low humidity.
