Common Names: Pyramid lanceolata, mosaic turmeric

Family & Genus: Pterophyllaceae

Native Range: Brazil, Costa Rica

Morphological Features:

This plant typically grows between 60 cm and 100 cm tall. Its leaves can reach up to 50 cm in length, with a grayish-green color and slightly darker edges. The leaves feature alternating dark green stripes along the main vein, parallel to the lateral veins, and have a brown or purple underside with wavy patterns. The flowers are light yellow in color.

Growth Requirements:

It thrives in warm, humid, and partially shaded environments. It is sensitive to cold and does not tolerate dry conditions or direct sunlight. The ideal growing temperature ranges from 22°C to 28°C.

Common Issues:

This species is prone to leaf spot, leaf blight, and infestations by whiteflies and scale insects. It is very sensitive to temperature fluctuations; when exposed to cold, its leaves may curl at night. A warm, moist, and semi-enclosed environment is essential for its health. During hot and dry summer and autumn periods, the fronds may turn yellow if humidity levels drop. To maintain healthy growth and vibrant foliage, it's important to keep the air around the leaves consistently moist. Overwintering requires temperatures above 10°C. It grows best in loose, well-drained soil and has low fertilizer needs. Excessive fertilization can cause leggy growth, reduce ornamental value, and even lead to deformed shapes. Therefore, fertilization should be done carefully and sparingly.

Propagation:

Reproduction is commonly done through ramets or tissue culture. In spring, plants can be repotted using fresh soil. After removing the plant from its pot, the roots are cleaned and replanted in new soil. It’s recommended to plant 3 to 5 individual plants per pot for optimal growth.

Cultivation Tips:

For potted plants, use a mix of humus soil (or peat soil) and garden soil in equal parts. Keep the soil consistently moist during the growing season, but avoid waterlogging. During hot and dry weather in summer and autumn, mist the leaves twice daily to maintain humidity and enhance leaf shine. Fertilizer requirements are minimal. Too much fertilizer can result in excessive growth, dull leaf color, and even lodging, which reduces the plant’s visual appeal. Apply a diluted fertilizer once a month during the growing season, and stop fertilizing by late autumn. Reduce watering and move the plant indoors in October, ensuring the winter temperature remains above 10°C.

Landscape Uses:

This plant is ideal for indoor decoration, such as in living rooms, studies, and bedrooms. It also works well in public spaces, like corridors and indoor flower beds, where it can add a touch of greenery and elegance.
