Care information

Tentative ID of the variable species terminalis, from eastern Ecuador.

Grows upright, slowly on a sturdy stem. Flowers periodically for me, and my mother plant (NFS last photo) is about 10 inches tall, so it doesn't get too out of control.

This plant produces pearl bodies or
crystoliths on the leaf surfaces. That isn't a plant pest!

You will receive a similar, but non-exact plant. They all look quite similar. Shipped bare-root.

Unknown humidity requirements, though it has done well outdoors in Z10a FL with dips to the low 20%RH.
Low to medium light

Plant Details
Airflow
Medium — Essential for "wetish" setups. Needs regular air exchange or internal circulation fans to prevent water from sitting on leaves, which helps avoid rot and fungal issues.
Family
Acanthaceae
Growth strategy
Terrestrial
Humidity
60–80% — Suitable for "open-top" or partially ventilated terrariums. While higher than average household humidity, these plants are adaptable and less prone to leaf melt if the environment fluctuates slightly.
Lighting
Bright — Requires high-output lighting to maintain vivid color expression (especially for reds, purples, and variegation) and to ensure shingling habits stay tight and compact.
PH
6.5–7.5 — Neutral: Suitable for hardy species that are less sensitive to water chemistry. This range is common in setups using tap water or inert substrates like clay pebbles and stones.
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
