About Calathea Network Gold

Goeppertia musaica 'Gold' · also called gold network calathea, golden mosaic calathea · houseplant

Goeppertia musaica 'Gold' (Calathea 'Network') is prized for its mosaic of tiny rectangular markings forming a fine network across rounded leaves, here warmed with golden-yellow tones. A compact, pet-safe prayer plant from Brazilian forests, it craves bright indirect light, steady warmth, high humidity, and evenly moist, well-draining soil to keep its intricate patterning sharp.

Preferred mix: Light, well-draining, moisture-retentive mix

Watch for — Leaf curling: Usually thirst or dry air. Check that the soil has not dried out and raise ambient humidity.
