About Calathea Lietzei

Goeppertia lietzei · also called white fusion calathea, Calathea lietzei · houseplant

Calathea Lietzei (Goeppertia lietzei) is the parent of the cultivar 'White Fusion', a slender prayer plant with wavy leaves marbled in white, green, and grey-green over purple undersides. Compact and elegant, it is pet-safe but notably fussy about humidity and pure water — rewarding precise care with striking variegated, night-folding foliage.

Preferred mix: Light, airy, moisture-retentive mix

Watch for — Root rot: This species rots quickly if left soggy. Use an airy mix, a draining pot, and let the surface dry slightly between waterings.

Why calathea lietzei needs this mix

Drainage and the pot

Use a pot with a drainage hole but a less-porous material (plastic or glazed) so it does not dry too fast. Bottom-watering keeps the mix evenly moist without sogging the crown.
