SPATHAGLOTTIS

ORCHIDS ASIA provides a range of orchids like Dendrobiums, Arandas, Arantheras, Mokaras, Vandas, Cattleyas, Phalenopsis, Oncidiums, Cymbidiums and other intergenerics. Plants in small, medium, and blooming sizes are available.
The “common” name for Spathoglottis is “Ground Orchids” even though there are several other genera that can be planted directly in the ground as landscape plants. These orchids are terrestrials found in the tropics of Asia.

LIGHT:

They like high light; some people even put them in direct sunlight. (But to be on the safe side, don't!) They also appreciate a fair amount of humidity; 60-70% is ideal.
If grown in greenhouses, 750 fc (150 PAR = micromol/sq m/sec) for the youngest plants coming out of flask or grown in plug trays; 2,000 - 5,000 fc (400 - 1,000 PAR = micromol/sq m/sec) or speckled sunlight protected from the hottest direct sunlight of the day is good for landscape or outdoor container growing.
Slowly acclimatize the plants to higher light levels when young plants are transitioned to outdoors. Flowering should occur throughout the year on the most modern hybrids / clones since they were bred for more compact foliage and larger more colorful flowers.

WATERING:

Spathoglottis require good drainage in the media, so after a thorough watering allow the media to dry on top but you do not want the container to dry out altogether. Do not allow to sit in water.
Water thoroughly in the morning once to twice weekly depending on your cultural conditions (light, temperature, humidity, air movement, etc.) allowing the top of the media to dry slightly between waterings. If the potting media is top-dressed with expanded slate, the area next to the pseudobulbs will dry out nice and quickly.

FERTILIZING:

Spathoglottis like fairly high feedings of fertilizer @ 200 - 300 ppm N every watering. Outdoors, a slow release fertilizer such as Palm 12-4-12, or Nutricote or Osmocote with full micros can be used in the 4 - 6 month release formulations. Apply according to the bag’s suggestions for herbaceous ornamental plants.

TEMPERATURE:

Spathoglottis are generally “warm” growing plants liking temperatures up to the high 80̊s F (30̊C) and they can tolerate temperatures down into the upper 50̊s F (15̊C). Keep in mind – the more air movement, the warmer the plants can be and the higher light levels they will accept without turning yellow; and if it is too cold, the pot stays too wet and the growth will suffer.
Foliage may burn below 50° F (14°C) - containers can be protected by moving or covering; landscape plants can be covered with light weight frost blankets. New growth will replace the old burned foliage if frost damages the plants, but protect from freezing.

POTTING MEDIA:

The plants are very forgiving as to the potting media. We use a media based on 75% high quality soilless mix used for hanging baskets and larger containers mixed with 25% our orchid potting media which incorporates expanded slate. Outdoor landscaping media can incorporate more orchid media for drainage - New Zealand Pinus radiata bark, perlite, sphagnum moss, and various other components.
The mix is very free draining but holds more moisture than regular media for epiphytic orchids. I plant allowing the topmost roots coming out of the pseudobulbs to be exposed and then top-dress with a couple of layers of straight expanded slate so that the area immediately around the pseudobulbs remains on the dry side. Do not bury the pseudobulbs. Potting containers can be in the 2 - 4 gallon size (8” - 12” diameter).

BLOOMING

Blooms typically are produced when the pseudobulbs mature. If the temps fall below 60° (15° C) for extended times, the plant may revert back to growth stage and flowering may be delayed.

Spathoglottis plicata-Varieties

SPATHOGLOTTIS-includes about 40 species occurring from India across southeast Asia, China, Malay Archipelago, New Guinea, Australia and the islands of the south-west Pacific Ocean. New Guinea has the largest number of species;Peninsular Malaysia, Borneo and the Philippines each have six; Thailand has five; Java three and there are two each in Sumatra and Australia.
The name Spathoglottis comes from the Greek spathe– a spathe and glotta– tongue, and refers to the broad lamina of the lip.

Colour:

White, Violet/Lavender, Light pink, Orange-Yellow.
Spathoglottis plicata or Ground orchid, native of Southeastern Asia to the Philippines, is the common species of Orchid which blooms round the year.
This easily grown terrestrial herb has pretty, arching broad leaves with prominent parallel veins and a few or large cluster of small flowers at the end of a long stalk as tall as 1 metre arising from a basal leaf axil.
The flowers are seen from the more common purple to white, yellow, peach, pink and magenta shades. The leaves emerge from round pseudo bulbs that become increasingly multiple and larger as the orchid matures. Ground orchids can be grown as potted plants and also do well in beds and borders.

Recommended species:

Spathoglottis bulbosa:

This species, from New Guinea, has large pseudobulbs up to 6cm across. Grown in full sun, the inflorescences can reach 60cm long with a large head of flowers. The flowers are magenta purple, with the sepals and petals paler at the base. Both this species and S. plicata in all its colour forms are good plants for a home garden. The same conditions apply to both species.

Spathoglottis duranii:

This desirable deciduous species has a 60cm-tall flower spike bearing numerous bright magenta flowers with a yellow callus, with four or five open at a time.

Spathoglottis kimballiana:

This species occurs in Borneo and the Philippines, from sea level to 300m in full sun.

Spathoglottis kimballiana var.angustifolia:

With narrower leaves than the typical species, is also grown. The inflorescence is up to 60cm tall, with several bright yellow flowers, each 8cm across, produced in April to July.

Spathoglottis affinis (syn.S. lobbii):

Occurring from Myanmar to Vietnam, Malay peninsula and Java, this species grows in the open at 600–1,000m. Usually leafless when in flower, it has seven to eight bright yellow flowers out at any one time, spaced 4cm apart. This plant can bloom for 8–10 weeks, producing more than 30 flowers on one spike.

Spathoglottis vanoverberghii:

Endemic to the Philippines, this species grows at elevations of over 1,000m. The inflorescence is erect but shorter than the leaves, bearing up to 10 bright canary yellow blooms 3cm in diameter but only two are open at any one time.

Breeding Spathos:

At present, there are 84 registered grex names for Spathoglottis. The first recorded Spathoglottis hybrid was S.Aureo-vieillardii made by Veitch in 1897, a cross between S. aurea and S.vieillardii(syn.S.plicata ‘Vieillardii’). The ‘green pod’ time for harvesting is 45 days after pollination in hot weather; 55 days in cool conditions.
