About Calathea Louisae 'Maui Queen'
Goeppertia louisae 'Maui Queen' · also called Calathea Maui Queen · houseplant
'Maui Queen' is a louisae cultivar with elongated green leaves marked by a bold pale-green to creamy feathered brushstroke down the centre, set over wine-purple undersides. A prayer plant, it folds upward at night. It needs warmth, even moisture, high humidity and bright indirect light, and resents hard tap water and chill indoors.
Preferred mix: Light, moisture-retentive, aerated mix
Watch for — Curling leaves: A sign of underwatering or dry air; leaves curl to conserve moisture. Check the soil is evenly moist and increase ambient humidity.
Why calathea louisae 'maui queen' needs this mix
Calathea Louisae '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 Louisae '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.
