Goeppertia kegeljanii

The network prayer plant is a tropical perennial evergreen native to the Brazil rainforests and thrives in warm and humid conditions. The plant has a intricate mosaic-like leaf pattern and is highly prized as a houseplant. It is a member of the prayer plant family (Marantaceae).

This plant prefers partial shade and moist, well-drained potting mix with an acidic to neutral pH. It is recommended to incorporate perlite or vermiculite with the potting mix to encourage good drainage. Water regularly with distilled water or rain water since the fluoride in tap water can cause the leaves to develop brown edges. It is frost intolerant and is winter hardy in USDA Plant Hardiness Zones of 11 to 12. This plant requires a humidity level of at least 60% and temperatures between 60 to 80 degrees Fahrenheit.  The plant is intolerant to sudden temperature changes and drafts. To increase the humidity in your environment place the plant on a wet pebble tray or invest in a humidifier. Fertilize the plant every month during the growing season with a balanced houseplant fertilizer.  Dust on the leaves can slow photosynthesis. It is best to remove the dust on a regular basis with a clean cloth.  Division is recommended for propagation.

The network prayer plant grows upright and has a clumping habit with a rhizomatous root system. It grows from 1 to 2 feet tall and equally as wide. The leaves emerge from the long stalks and are thick, waxy, glossy, heart-shaped, and light green with a complex pattern of fine dark green lines. The leaves may fold at night and then reopen at sunrise. This is known as "nyctinastic" movement and is caused by a change in light intensity and temperature change. This plant can produce flowers, but they are small and insignificant. The foliage is the main attraction.

The network plant is used for its ornamental value and is popular for use in homes or offices. 

Insects, Diseases, and Other Plant Problems:  Monitor for spider mites, aphids, scale insects, and mealybugs. Overwatering can cause root rot, and underwatering and tap water can cause brown leaf edges and brown leaf tips. Direct sunlight can cause leaf burn. Leaf spot can occur from wetting the foliage when watering. Provide good circulation to prevent fungal and bacterial infections.

The network plant is non-toxic to pets and humans; however, the sap can cause skin irritation. Wear protective gloves when handling this plant.
