It finally flowered! This is a Cosmianthemum based on floral morphology.

This is not a challenging plan to grow. It handles high humidities and low airflow quite well. it also did fine in lower humidity levels, including outdoors here in Florida.
I'm not sure what the maximum height and size is. it does not grow terribly fast.

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
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.
