Care information

*Rhaphidophora cf. korthalsii* is an unidentified but closely related form to *Rhaphidophora korthalsii*, a widespread shingling aroid native to Southeast Asia. This species is known for its small, round to oval juvenile leaves that press tightly against vertical surfaces. With maturity, the leaves can enlarge considerably and may develop more elongated or altered shapes depending on conditions. The “cf.” designation indicates uncertainty in the exact identification, but it is clearly allied to *R. korthalsii*.

**Light Requirements:** Bright, indirect light. Avoid harsh direct sun.
**Humidity Requirements:** Moderate to high, 60–85%. Thrives in terrariums, cabinets, or greenhouse environments.
**Temperature Range:** 65–85°F (18–29°C). Keep above 60°F (16°C).
**Growth Habit:** Shingling climber with juvenile leaves tightly appressed to climbing surfaces; mature leaves enlarge and elongate with vertical growth.
**Soil:** Well-draining tropical aroid mix with bark, perlite, or coco chips. Mounting is also suitable for maintaining shingling form.
**pH:** Slightly acidic to neutral, 5.5–6.5.
**Size:** Juvenile leaves 2–4 cm; mature leaves can grow substantially larger when provided with adequate climbing support.

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
Araceae
Growth strategy
Epiphyte
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
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
Cutting
Size
Large
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.
