Calathea Ornata Care
Size & Growth
Growing as a house plant the potted pinstripe plant reaches about 1′ or 2′ feet high and wide.
The leaves are colorful and beautifully patterned. Typically, younger leaves are green on the top with striking bright pink lines located between the lateral veins.
The undersides of leaves are purple.
As plants mature, the lines lose their pink color and become white.
Fully mature, flowering plants usually do not have lined leaves. Alternately, the white lines may disappear, and yellowish green brush patterns may take their place.
Mature plants may also lose the purple hue of the leaves’ undersides, which may transition to a deep green.
NOTE: Another attractive Calathea with interesting leaves is the ‘Rattlesnake plant‘.
Flowering & Fragrance
Calathea ornata is grown for its attractive, colorful foliage.
When mature plants do flower, the blossoms are colorful and attractive but are secondary to the brilliant leaves.
The orange flowers are oval-shaped and grow on spiral bracts.
Light & Temperature
Because these are understory plants in their natural settings, Pinstripe Calathea naturally prefers a shady location and plenty of humidity.
Bright indirect light enhances the colors of the foliage, but extended periods of direct sunlight are intolerable.
Calathea ornata needs protection against high winds and cold. The best temperature for this plant is between 65° and 75° degrees Fahrenheit.
Never allow the temperature to drop lower than 60° degrees Fahrenheit.
Watering & Feeding
These tropical plants like humid conditions, and appreciate misting several times a week. It’s also a good idea to keep Calathea containers on pebble trays filled with water to maintain a high level of humidity around the plants.
Keep the soil moist but not soggy at all times. Allow the top inch of the soil to dry before watering.
Feed twice a month with a diluted solution of balanced fertilizer. Don’t fertilize during the winter months, but do fertilize during the growing season which runs from April through October.
Soil & Transplanting
Calathea does well in a moist soil potting mix consisting of one part perlite and two parts peat.
Repot in the springtime every other year.

- Trim off dead or withered leaves at the base of the stem.
- Spray the leaves of your Calathea several times a week.
- Wipe the leaves clean of dust as needed.
How To Propagate Calathea ornata
As with most plants growing from rhizomes, propagation by division is the easiest method.
When repotting Calatheas split plants into several more to increase your collection.
