Paph tigrinum (1990: Koopowitz & N. Hasagawa)
Habitat Information:

Geographic Distribution: Along the border of Burma and China

Elevation:

Blooming Season (North): Spring

Light requirements: Medium to bright indirect light. With more light, increase air movement and water.

Temperatures : Summer highs in the low 90s, lows in the mid 40s in the winter.

Substrate: Terrestrial or Epiphytic. Although Cribb (1998) and Birk (2004) indicate that this species typically grows on rocky hillsides, the species has recently been discovered growing in trees, rooted in moss. See photos below.

Water: Moisture is high year round, but summer is the monsoon season and is especially wet.

Humidity: High

Paph tigrinum is surprisingly easy to grow. They grow quickly and produce new growths at a tremendous rate. One year ago, this was a healthy 3 growth plant, and today is a healthy 7 growth plant (plus a small start). This particular plant ('burning bright') was subjected to very high temperatures, cool temperatures, excessive dryness, and an attack of mites, and shrugged off all of these problems to produce the two blooms shown at left.

Tigrinum plants of one or two growths are slightly more difficult to bloom. They may produce buds, but the buds usually die before maturing. With these young plants, and indeed any Paph. tigrinum that you would like to bloom, be very careful to keep the leaves and the crown of the plant dry! When watering, water directly into the pot only.

Otherwise, tigrinum can be treated much like any other Paph species. Bright but indirect light, plenty of air movement and moisture. There are reports of tigrinums grown well in dry conditions as well as in wet. If kept overly moist, the leaves are prone to bacterial infection and crown rot.

The following series of photos presents the bloom sequence of my Paph. tigrinum 'burning bright'. The photos are dated, covering a 6 month time span.

This photo shows Paph. tigrinum growing in its natural habitat in western China. As you can see, this particular plant is growing as an epiphyte, approximately 10 feet above the forrest floor. Elevated in this way, the plants are subject to constant air movement.

In conditions such as these, the species receives moisture from the fog and clouds in addition to the rainfall. However, the mossy substrate drains well and dries relatively quickly. Direct sunlight is blocked by the forest canopy.
