Pleurothallis marthae xanthinum

A color form of the epiphyllous Pths. marthae, producing a compact glomerule of flowers clustered on the surface of a large, glossy, lanceolate leaf. The ovate, concave sepals are more openly spread than in the type, each with a small lip visible at the center — the same distinctive head-like inflorescence rendered in a uniformly pale, luminous tone.

• Light: Bright indirect light with 50–65% shade cloth; avoid direct sun, which can scorch the broad, glossy leaf surface.
• Temperature: 50–68°F (10–20°C); a Cool to Intermediate grower with a minimum tolerance around 46°F (8°C). Cool nights promote consistent blooming.
• Humidity: 75–90%; maintain consistently high humidity — a humidifier or enclosed greenhouse environment is strongly recommended.
• Watering: Keep the medium evenly moist; never allow to dry out completely, but ensure excellent drainage to prevent root rot.

Additional Notes

Best grown in a small pot with a fine, moisture-retentive mix (sphagnum or fine bark with perlite). Plants are shipped bare root and well-established.
