About Caladium 'White Queen'
Caladium bicolor 'White Queen' · also called White Queen Caladium · houseplant
Caladium 'White Queen' is a fancy-leaf caladium with striking near-white, paper-thin heart-shaped leaves veined and flushed in crimson-pink over green margins. Grown from a tuber, it puts on a vivid show in warm, humid, bright-indirect conditions through the growing season, then dies back to dormancy. The pale leaves need gentle light to keep from scorching.
Preferred mix: Rich, moisture-retentive yet well-draining mix
Watch for — Crispy brown edges: Low humidity; raise it with a humidifier or pebble tray, and keep the soil evenly moist.
Why caladium 'white queen' needs this mix
Caladium 'White Queen' hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Caladium 'White 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.

- A free-draining, gritty mix dries too fast for caladium 'white 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 caladium 'white queen' dry out. It needs a moisture-retentive but still airy blend.
