How to care for Pinstripe Calathea
Goeppertia ornata · Marantaceae
Deep green, almost black leaves pinstriped in fine pink lines, like they were drawn on by hand. The stripes fade to white as leaves mature. This is one of the fussier calatheas — it makes an unforgettable plant for growers willing to keep humidity high and water pure. Water roughly every 5 days while it's growing (about every 9 in winter), give it a bright room away from the window, kept above 61°F (16°C) — it wants humid air.
Care at a glance
Water with filtered or rainwater when the top centimeter dries; never let the root ball dry through.
A bright spot with zero direct sun; the dark leaves scorch and fade easily.
Very dilute balanced fertilizer monthly — this species is especially salt-sensitive.
Mistakes that kill this plant
- Treating tap water as fine — buildup slowly ruins every leaf.
- Big swings between soggy and bone dry.
- A cold, drafty winter spot.
Seasonal tips
- Group it with other humidity lovers or run a humidifier from autumn onward.
- Hold off on repotting until it is clearly rootbound — it hates disturbance.
- Flush the pot with clean water each spring to clear mineral buildup.
