General information for this group :
Most members of this group require very similar conditions, since they share common habitats. They are easy to grow and bloom when provided with the right environment. You can find some of the "most interestingly colored and patterned" flowers in this group. The initial discussion is for Vandas and any hybrid which has Vandas in it's background. For subgroups that have additional specific 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 : Vandas and their hybrids

Covers these genera : Aerides (Aer.) , Aeridovanda (Aerdv.) , Arachnis (Arach.) , Ascocenda (Ascda.) , Camarotis (Cmt.) , Christieara (Chtra.) , Doricentrum (Dctm.) , Esmeralda (Esmrls.) , Kagawaara (Kgw.) , Neostylis (Neost.) , Renades (Rnds.) , Renantanda (Rntda.) , Renanthera (Ren.) , Rhynchorides (Rhrds.) , Rhynchostylis (Rhy.) , Robiquetia (Rbq.) , Ronnyara (Rnya.) , Trichoglottis (Trgl.) , Vanda (V.) , Vandachostylis (Van.) , Vandaenopsis (Vdnps.) , Vandofinetia (Vf.) , Vascostylis (Vasco.)

Light :
Most Vandas appreciate bright to high light. The range would be similar to that for Cattleyas and higher. This is often difficult to provide on a windowsill, but luckily these plants will be quite happy being summered outdoors, hanging from a tree branch. This treatment is usually sufficient to get them into bud, so that the flowers can be enjoyed once the plants return indoors.

Temperature and Humidity :
Most members of the group prefer intermediate to warm temperatures with very few exceptions. But remember that the higher the temperature, the higher the humidity needs to be, so daily misting of the roots may be necessary, especially when the plants are summering outdoors. If you notice that the leaves are starting to dessicate, then shortage of moisture is likely the cause.

Media :
When grown in baskets, most of these plants will not require any media at all. If you do decide to pot them, then use a clay pot with either spongerok, lava rock, or some other coarse medium that will not break down. The coarser the medium, the less likely you will have to worry about root rot.

Water :
These plants appreciate regular misting of the root systems if grown in baskets. Use rainwater if possible. If grown in a pot, then douse thoroughly each time you water to ensure there is no chemical/fertilizer residue remaining between waterings.

Fertilizing :
A single properly balanced fertilizer (ie. 15-5-15) is just fine for the entire year.

Blooming :
Many of these plants will bloom several times per year if the growing conditions are good. It is not unusual to have a healthy plant bloom for six months or more each year.

Caution :
Most of these plants arrive directly from Thailand. It is important for you to ensure you have a plant that is properly adjusted to the climate that you are in. If you live in the tropics, then you have no worries. However, if you live in a temperate zone, or colder, you may have some serious problems trying to get these plants to acclimate quickly. The easiest way to confirm that the plants have been acclimated is to examine the root system. If it is fine and wiry, then the plant has just arrived. In temperate regions this root system is completely replaced by thick, fleshy roots, and that is what the plant needs to survive.

Subgroup : Compact growers

Covers these genera : Acampe (Acp.) , Ascocentrum (Asctm.) , Cleisostoma (Cleis.) , Gastrochilus (Gchls.) , Neofinetia (Neof.) , Pomatocalpa (Pmcpa.) , Sarcochilus (Sarco.) , Sedirea (Sed.)

Description : These plants do not grow exceptionally tall, and they do very well in pots. However, a coarse, free-draining medium is required. We use our medium bark mix for these types. This allows ample air to the root system, while still providing the humidity they require. Several members of this groups have delightful fragrances, such as Neofinetia, Sarcochilus, and Sedirea.

Same as for Vandas, except :

  • Preference for growing in pots in coarse media. Choose pots that are same width and height.
  • Prefer moderate to bright light, but will burn in high light.
  • Have more of a tendency to form clumps, rather than spindly growths.

  • Subgroup : Miniatures

    Covers these genera : Dyakia (Dy.) , Haraella (Hal.) , Schoenorchis (Schoen.) , Tuberolabium (Tblm.)

    Description : These are excellent terrarium candidates, since it is much easier to provide ample humidity under those conditions.

    Same as for Vandas, except :

  • Haraella and Schoenorchis do well on treefern slabs.
  • Dyakia and Tuberolabium do well in small pots, or a combination of slabs in pots.
  • If growing on slabs, then make sure to mist often to prevent dessication of leaves.
  • Content with moderate to bright light. Leaf color is a good indicator of adequate light levels.
  • Excellent terrarium candidates.

  • Subgroup : Mounted Types

    Covers these genera : Paraphalaenopsis (Pps.) , Pelatantheria (Pthia.) , Seidenfadenia (Sei.) , Thrixspermum (Tx.)

    Description : Except for Paraphalaenopsis, these are primarily ramblers, producing roots at every junction. Hence they all do well on treefern or cork slabs, allowing extra room for the ramblers.

    Same as for Vandas, except :

  • Content with moderate to bright light.
  • Water thoroughly once per week, with additional root mistings in between if the humidity levels are low.
