Angraecum rubellum

Angraecum rubellum (described by Bosser in 1988) is an accepted orchid species native to eastern Madagascar, primarily thriving as a miniature epiphytic subshrub in humid tropical forests.

Features:

• Morphology & Habitat
  A tiny, cool-growing epiphyte often found perched without a distinct stem. Its leaves are obovate to elliptic, strongly keeled beneath, and tinged green with red. Flower clusters (1–3 blooms) emerge from relatively long inflorescences hidden among foliage.
• Flowers
  The blooms measure around 1.5–2.5 cm long. They are fleshy, whitish to slightly pink, covered with papillose (tiny thorn-like) hairs, giving them a textured appearance.

Care Tips:

• Light: Provide bright, indirect light. Avoid direct sunlight to prevent leaf scorch.
• Temperature: Best grown under intermediate to warm conditions, with daytime temperatures between 20–28 °C (68–82 °F) and nights around 18 °C (64 °F). If temperatures exceed 28 °C, increase humidity and air movement.
• Humidity: Maintain high humidity, ideally 75–80%. Regular misting or placement in a humid growing area is beneficial, but always pair high humidity with good airflow.
• Watering: Water thoroughly when the potting medium is nearly dry. Use rainwater or distilled water to prevent mineral buildup. Ensure rapid drainage to avoid root rot.
• Substrate: Use a well-draining mix of fine fir bark, sphagnum moss, and perlite. Mounting on cork or tree fern, or growing in baskets, improves air circulation around the roots.
• Fertilization: Feed with a balanced orchid fertilizer at half strength every 2–4 weeks during active growth (spring and summer). Reduce or stop feeding during the dormant period.
• Air Circulation: Keep air moving around the plant at all times to prevent fungal and bacterial issues, especially in high-humidity conditions.
