Paphiopedilum tigrinum

Paphiopedilum tigrinum

Paphiopedilum tigrinum is a rare and critically endangered slipper orchid native to parts of Myanmar and Yunnan, China. It’s known for its striking tiger-striped petals and unique pouch-shaped lip. As a terrestrial-to-lithophytic orchid, it requires specific care to thrive in cultivation, often best suited for experienced growers or those who can closely replicate its natural habitat.

🐯 Paphiopedilum tigrinum Cultivation Guide

🔆 Light

• Type: Moderate to bright indirect light.

• Ideal Conditions:

  • East-facing windows.

  • Dappled sunlight under shade cloth (50% shade).

• Avoid direct sun which can scorch leaves.

🌡️ Temperature

• Daytime: 20–28°C (68–82°F)

• Nighttime: 12–18°C (54–64°F)

• Needs a slight cooling at night to initiate blooming.

💦 Humidity

• Optimal: 60–80%

• Use humidity trays, misting, or a humidifier if indoors.

• Ensure air movement to avoid fungal issues.

💧 Watering

• Frequency:

  • Water when top of the medium just begins to dry.

  • Keep evenly moist, not soggy.

• Type: Use rainwater, RO, or distilled water to avoid salt/mineral buildup.

• Avoid water on the crown to prevent rot.

🌱 Growing Medium

• Recommended Mix:

  • Fine to medium bark

  • Perlite or pumice

  • A small amount of sphagnum moss or leaf litter

  • Crushed limestone (for calcium – mimics natural habitat)

• Must be well-draining yet moisture-retentive.

🪴 Pot Type

• Plastic or clay pots with good drainage holes.

• Shallow pots preferred, as roots are not deep.

🌸 Flowering

• Blooms: Typically in summer to early autumn.

• Flower has tiger-like striping, with long, twisted petals.

• Cool nights help stimulate bud formation.

🧪 Fertilization

• Diluted orchid fertilizer (e.g., 1/4 strength 20-20-20) every 2–3 weeks during active growth.

• Use low-nitrogen fertilizer in late fall to encourage blooming.

• Flush the pot once a month with plain water.

🍂 Dormancy

• Paphiopedilum tigrinum may slow growth in cooler months.

• Reduce watering slightly but do not let dry out completely.

• Keep in brighter light and slightly cooler temps during winter rest.

⚠️ Tips & Warnings

• Do not overpot – they prefer tight pots.

• Avoid soggy mix – root rot is the most common killer.

• No back bulbs – each growth blooms once, then declines.

• Highly sensitive to salt buildup – flush regularly.
