Paphiopedilum canhii (often abbreviated Paph. canhii) is a rare and miniature species of slipper orchid native to limestone regions in northern Vietnam and Laos. It's part of the Paphiopedilum genus, known for their unique pouch-like flowers and relatively slow growth.

This species has some specific needs, especially due to its natural habitat, and can be a challenge to cultivate. Here's a detailed guide to help you grow Paph. canhii successfully:

🔍 Basic Information

• Origin: Northern Vietnam & Laos

• Elevation: ~600–800 meters

• Climate: Subtropical; warm to intermediate temperatures

• Growth Habit: Terrestrial to lithophytic (grows in crevices of limestone cliffs)

• Size: Very compact, small species

• Bloom Time: Typically late summer to autumn

• Flowers: Small but striking, with dark, mottled patterns

🌱 Cultivation Guide

🪴 Potting Mix

Since Paph. canhii is a limestone-growing species, the potting mix should mimic its natural environment:

Recommended media:

• Fine-grade bark (or small Orchiata)

• Crushed limestone or dolomite (essential)

• Perlite or pumice (for drainage)

• Charcoal (optional)

• Sphagnum moss (in small quantity, if you need more moisture retention)

⚠️ Avoid overly organic or moisture-retentive mixes. Drainage is critical.

💧 Watering

• Water regularly, but let the potting mix dry slightly between waterings.

• Overwatering can lead to root rot.

• Use rainwater or low-mineral water.

• Watering frequency: ~2 times per week, adjust based on season and humidity.

🌡️ Temperature

• Day: 22–28°C (72–82°F)

• Night: 15–20°C (59–68°F)

• Avoid extremes; it dislikes both heat waves and cold snaps.

💡 Light

• Bright, indirect light is ideal.

• Avoid direct sun, which can scorch the leaves.

• Ideal location: East-facing window, or shaded grow lights (2000–2500 foot-candles).

• Too little light will prevent blooming.

💨 Humidity & Airflow

• Humidity: 60–80%

• Good air circulation is vital to prevent fungal issues.

• Consider a fan or open windows if growing indoors.

🌸 Fertilization

• Use a balanced orchid fertilizer (20-20-20 or similar) diluted to 1/4 to 1/2 strength.

• Fertilize every 2–3 weeks during active growth.

• Use a Calcium and Magnesium (Cal-Mag) supplement if your water is soft.

🔁 Repotting

• Repot every 1–2 years, ideally in spring.

• Always repot if the mix is breaking down or if roots look unhealthy.

❗ Tips & Warnings

• Limestone is essential. This species grows in calcareous environments.

• Compact growth means it does well in small pots—don’t overpot.

• Difficult to find; often only available from specialty nurseries.

• Slow-growing—patience is key.
