The Calathea ornata, also known as the Pinstripe Plant, is a captivating houseplant known for its distinctive foliage. Its dark green leaves feature striking thin stripes, often in shades of pink or creamy white, which lend it its common name. Originating from tropical Central and South America, this plant brings exotic elegance to indoor spaces. Its unique appearance makes it a favored choice for adding vibrant patterns to collections.
Pinstripe Plant Care Essentials
Light
Pinstripe Plants thrive in bright, indirect light. Placing them near an east, west, or north-facing window is ideal, as these locations provide ample light without harsh direct sun exposure. Direct sunlight can be too intense for their delicate leaves, causing stripes to fade, scorch marks, or browning. Filtering strong light with sheer curtains protects the foliage while providing necessary illumination.
Watering
Pinstripe Plants require consistent moisture; the soil should remain evenly moist but never waterlogged. Water when the top inch or two of soil feels dry. Use filtered, distilled, or rainwater, as these plants are sensitive to minerals and chemicals in tap water, which can lead to brown leaf tips and edges. Standing water can lead to root rot.
Humidity
Pinstripe Plants require high humidity, ideally above 60%, due to their tropical rainforest origin. Low humidity often causes brown and crispy leaf edges. Increase humidity by placing the plant on a pebble tray, grouping it with other plants, or using a cool-mist humidifier. Misting provides only temporary humidity and can encourage fungal issues if leaves remain wet.
Soil
A well-draining, moisture-retentive potting mix is needed for Pinstripe Plants. A peat-based soil mix rich in organic matter is recommended. A mix combining peat moss with perlite or orchid bark enhances drainage and aeration while retaining moisture. The ideal soil pH is mildly acidic, around 6.5.
Temperature
Pinstripe Plants prefer warm and consistent temperatures, ranging from 65 to 85 degrees Fahrenheit (18 to 29 degrees Celsius). They are sensitive to sudden temperature drops and cold drafts, causing stress and drooping leaves. Maintaining a stable indoor environment, away from open windows, air conditioning vents, or heating units, ensures their well-being.
Fertilizing
During the active growing season (spring and summer), Pinstripe Plants benefit from regular fertilization. Apply a balanced liquid houseplant fertilizer, diluted to half strength, every two to four weeks. Avoid fertilizing during dormant winter months, as growth slows and excess nutrients can accumulate, leading to root burn. Over-fertilization can also cause yellowing leaves or brown leaf tips.
Repotting Pinstripe Plants
Repotting a Pinstripe Plant is needed every one to two years, or when root-bound. Signs of being root-bound include roots emerging from drainage holes, stunted growth, or soil drying out faster. Repot in early spring, before active growth, to allow quicker recovery. Select a new pot one or two inches larger with adequate drainage. Gently remove the plant, loosen circling roots, and place it in the new pot with fresh potting mix at the same depth.
Propagating Pinstripe Plants
Pinstripe Plants are most effectively propagated by division, often during repotting. Unlike many houseplants, Calatheas do not root from stem or leaf cuttings due to lacking nodes. To divide, carefully remove the mother plant and separate rhizomes, ensuring each new section has healthy roots and leaves. Plant divisions in individual pots with fresh, well-draining soil, providing warm, humid conditions and indirect light for establishment.
Common Pinstripe Plant Problems
Browning leaf tips and edges often indicate low humidity or sensitivity to tap water minerals. Increase humidity and use filtered or distilled water to alleviate this. Yellowing leaves indicate overwatering, which can lead to root rot if soil remains soggy. Allow soil to dry between waterings and ensure proper drainage to prevent this. Drooping leaves signal underwatering or exposure to cold drafts and sudden temperature changes.
Pinstripe Plants are also susceptible to spider mites and mealybugs, especially in dry conditions. Inspect leaf undersides regularly and treat infestations promptly with insecticidal soap or neem oil.
