Care information

You will receive a similarly sized or larger specimen to the plants in the photos (video is my mother plant as an example).

I've managed to acclimate these to houseplant conditions easily. Probably an undescribed species.

Flowers regularly in my tank, self-fertile and produces seed successfully.

Moderate light, good drainage, good airflow, and probably high humidity, though it was fine in ambient air. Seriously, not much is known about this one, haven't seen others with it yet.

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
Acanthaceae
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
Small
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
Moist — Substrate should be kept consistently hydrated but never "soggy." This allows for critical oxygen to reach the root zone, preventing hypoxia and rot.
World
Old World — Native to the Eastern Hemisphere: Africa, Europe, Asia, Australia, and surrounding islands.
