Care information

*Labisia posthumusiana* is a small understory plant native to humid tropical forests of Southeast Asia. It grows as a compact rosette from a short stem, producing narrow, elliptic leaves with a firm texture and smooth surface. Foliage is typically deep, dark color, with a glossy sheen and may show reddish tones along the midrib, margins, or underside depending on light and maturity. The plant remains low and slow-growing, making it suitable for terrariums, plant cabinets, or shaded greenhouse culture.

You will receive a single bare-root plant, grower’s choice. Listing photos are representative of the approximate size and form you will receive.

**Light Requirements:** Bright, indirect light to light shade. Avoid direct sun.
**Humidity Requirements:** Moderate to high, approximately 60–85 percent.
**Temperature Range:** 65–85°F (18–29°C). Keep above 60°F (16°C).
**Growth Habit:** Compact rosette-forming understory plant with short stems.
**Soil:** Moisture-retentive but well-draining tropical mix with organic matter.
**pH:** Slightly acidic, approximately 5.5–6.5.
**Size:** Leaves typically 8–15 cm long; plant remains compact in cultivation.

Plant Details
Airflow
Low — Specifically suited for sealed, stagnant environments. These plants do not require active ventilation or fans to prevent bacterial or fungal "melt."
Family
Primulaceae
Growth strategy
Terrestrial
Humidity
80–100% — The "Sweet Spot" for most rare tropicals and shinglers. This high-saturation environment is essential for aerial root attachment to hardscape and ensures that delicate foliage maintains its turgidity and sheen.
Lighting
Moderate — Prefers bright, filtered, or indirect light. This is the "sweet spot" for most terrarium species; however, direct sun or high-intensity LEDs will scorch delicate juvenile leaves.
PH
5.5–6.5 — Acidic (Optimal): The “Goldilocks” zone for most tropical terrarium plants, including Marcgravia. This range ensures maximum nutrient availability and mimics the natural decomposition of leaf litter on the rainforest floor.
Sales form
Rooted
Size
Medium
Temperature
70–85°F — Standard Tropical Range. This mirrors the natural understory of the rainforest, providing enough warmth for vigorous growth while remaining safe from the extreme heat that can bake a closed glass enclosure.
Watering substrate
Damp — These plants love high moisture levels; the substrate should stay wet to the touch at all times but should not be sitting in a stagnant, waterlogged state.
World
Old World — Native to the Eastern Hemisphere: Africa, Europe, Asia, Australia, and surrounding islands.
