About Calathea 'Maui Queen'
Goeppertia louisae 'Maui Queen' · also called Calathea 'Maui Queen', Maui Queen prayer plant · houseplant
Calathea 'Maui Queen' is a compact prayer plant grown for feathery green-and-cream variegated foliage that folds upward at night. It needs bright indirect light, evenly moist soil watered with filtered or rainwater, and 50-60% humidity. The ASPCA lists Calathea as non-toxic to cats, dogs, and horses, so it is pet-safe.
Preferred mix: Light, well-draining, peat-based aroid-style mix, slightly acidic to neutral
Watch for — Curling or rolling leaves: A sign the plant is too dry — either low humidity or underwatering. Keep soil evenly moist and increase ambient humidity with a humidifier or pebble tray.
Why calathea 'maui queen' needs this mix
Calathea 'Maui Queen' hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Calathea 'Maui Queen' comes from damp, shaded forest floors and has fine roots that scorch and brown the moment the rootball dries — the mix has to hold a steady reserve.
- Coir and compost give that reserve, while perlite keeps enough air that the constantly-moist mix does not turn anaerobic.
- Even moisture also keeps its thin leaves from crisping at the edges, which is this plant’s most visible stress signal.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons calathea 'maui queen' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A free-draining, gritty mix dries too fast for calathea 'maui queen' — you get crispy brown edges and frond or leaf drop within days of one missed watering.
- A pure, airless peat mix swings the other way: it holds water but suffocates the fine roots and rots the crown.
- Letting the mix dry to the point it shrinks from the pot is very hard to re-wet evenly and stresses the plant badly.
Using a sharp, fast-draining "houseplant" or cactus-leaning mix that lets calathea 'maui queen' dry out. It needs a moisture-retentive but still airy blend.
