Calathea makoyana, also known as the Peacock Plant or Cathedral Windows, is a Brazilian rainforest understory species prized for its translucent, patterned leaves and purple undersides. The short version: it’s a humidity‑hungry, water‑sensitive prayer plant with paper‑thin foliage that demands stable warmth and clean water.
🌿 Identity & Origin
-
Native to the Atlantic rainforest of eastern Brazil, growing in warm, shaded, humid understory conditions.
-
Formerly Calathea makoyana, now classified as Goeppertia makoyana.
-
Member of the Marantaceae (prayer plant family), so its leaves raise at night and lower during the day.
🍃 What makes it distinctive
-
Translucent, silvery-green leaves with dark oval “peacock feather” markings along the midrib.
-
Purple to burgundy undersides that glow when backlit.
-
Paper-thin foliage—beautiful but easily damaged by dryness, minerals, or sun.
-
Grows as a compact clumping perennial, typically 30–60 cm tall indoors.
🌱 Care Requirements (Yakima-friendly guidance)
Yakima’s dry air makes this species more challenging, but manageable with the right setup.
☀️ Light
-
Medium to bright indirect light (5,000–10,000 lux).
-
Never direct sun—its thin leaves scorch and patterns fade.
💧 Water
-
Water when the top 1–2 cm dries.
-
Use rainwater, distilled, or filtered water—tap fluoride causes brown edges.
-
Keep soil evenly moist but never soggy.
🪴 Soil
-
A peat-based, well-draining mix with perlite or bark for aeration.
-
Moist but not wet; roots hate stagnation.
🌡️ Temperature
-
Ideal: 18–24°C (65–75°F).
-
Damage occurs below 13°C (55°F).
💦 Humidity
-
Needs 60%+, ideally 70%.
-
In Yakima’s dry climate, use a humidifier or pebble tray.
-
Low humidity causes leaf crisping and curling.
