“Psalm Plants” refers to a group of houseplants known for their striking foliage and unique behaviors. Cherished for their ornamental value, they add natural beauty and dynamic interest to indoor spaces.
The Origin of the Name “Psalm Plants”
The common name “Psalm Plant,” or “Prayer Plant,” comes from nyctinasty, a botanical phenomenon of leaf movement over 24 hours. During the day, leaves lie flat to absorb light; as evening approaches, they fold upwards, resembling hands clasped in prayer. This rhythmic folding is driven by water pressure changes in specialized cells called pulvini. The spiritual connection links the name to themes in the Book of Psalms. While not a scientific classification, “Psalm Plant” generally refers to species in the Marantaceae family, including Maranta, Calathea, and Stromanthe, all native to South American tropical forests.
Caring for Psalm Plants
Caring for Psalm Plants, including Maranta, Calathea, and Stromanthe, requires mimicking their native tropical environments. Consistent conditions help these sensitive plants thrive indoors, maintaining their vibrant patterns and unique leaf movements.
These plants flourish in bright, indirect light conditions. Placing them near an east or north-facing window, or several feet away from a brighter window, is ideal. Direct sunlight can cause their colorful leaves to fade or develop brown scorched patches. Insufficient light, however, might lead to less vibrant coloration and less pronounced leaf movement.
Consistent moisture is important, but Psalm Plants are sensitive to both overwatering and prolonged dryness. Keep the soil evenly moist, allowing the top inch or two to dry slightly before rewatering. Use filtered, distilled, or rainwater, as tap water chemicals like chlorine and fluoride can cause brown leaf tips.
High humidity is crucial for Psalm Plants, which originate from humid rainforests. Aim for levels above 50%, ideally 60-80%. Increase humidity using a humidifier, a pebble tray, or by grouping plants. Insufficient humidity causes crispy leaf edges and curling.
Use a well-draining, moisture-retentive potting mix, such as a blend of peat moss, coco coir, perlite, or compost. Ideal temperatures range from 65-80°F (18-27°C); protect them from cold drafts.
During the spring to fall growing season, fertilize every two to four weeks with a half-strength balanced liquid houseplant fertilizer. Reduce or stop fertilization in winter. Yellowing leaves may indicate overwatering or poor drainage, while small or leggy leaves suggest inadequate light. Crispy brown tips often result from low humidity or tap water mineral buildup. Adjusting conditions addresses these issues.
