Care information

*Triolena hirsuta* is a Melastomataceae species native to Central and South America, typically found in moist tropical forests. It is recognized by its hairy stems and leaves, with the foliage displaying distinct venation and a softly textured, slightly fuzzy surface. The plant grows upright to lightly spreading and adapts well to warm, humid environments, making it suitable for terrariums, greenhouses, or shaded tropical plant setups.

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:** High, 70–90 percent. Thrives in humid terrarium or greenhouse conditions.
**Temperature Range:** 65–85°F (18–29°C). Keep above 60°F (16°C).
**Growth Habit:** Upright to lightly spreading plant with hairy stems and leaves.
**Soil:** Moist, fine-grained, well-draining tropical mix with perlite or moss.
**pH:** Slightly acidic, 5.5–6.5.
**Size:** Leaves typically 4–10 cm; plant remains small to medium depending on conditions.

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
Melastomataceae
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
New World — Native to the Western Hemisphere: North, Central, and South America plus the Caribbean
