Silver Leaf Monstera Monstera siltepecana

Silver monstera is a climbing, evergreen, epiphytic herbaceous perennial in the arum family (Araceae). It is native to the rainforests of southern Mexico and Central America. The species epithet refers to the place where the plant grew, the town of Siltepec, Chiapas, Mexico. This plant has become very popular as a houseplant because of its low maintenance and beautiful foliage. 

Silver Monstera has a trailing or climbing habit and grows 5 to 8 feet tall and 3 to 5 feet wide. There are two stages of leaf growth: juvenile and adult. Juvenile leaves are small, lanceolate, thick at the base with a pointed tip, and silvery green with dark green veins. As the plant matures, the adult leaves are larger, develop fenestrations (holes or windows), lose the silvery color and become dark green. The leaves will remain juvenile if the plant is allowed to trail in a container or hanging basket. When the plant is staked and begins to climb, the leaves become larger and greener with the fenestrations. A mature plant will have juvenile leaves at the base of the stem, and the larger, less silvery adult leaves will be at the top of the plant. The plant rarely flowers, but under the proper conditions it may produce a large white spathe and spadix.  

This tropical plant prefers bright, indirect sunlight; however, direct sunlight will scorch its leaves. It thrives in a warm and humid environment with temperatures between 60 and 95 degrees Fahrenheit. Consider placing the plant in a kitchen or bathroom to increase humidity levels to between 40 and 60%. Avoid cold drafts that can damage the leaves. Moist, well-drained and aerated potting mix are required for this plant to thrive. Water the plant thoroughly when the top 1 to 2 inches of soil are dry. Repotting may be required every 1 or 2 years. It may be propagated by stem cuttings.

The Silver Monstera performs best if planted in a container and allowed to climb on a bamboo or moss pole so that the juvenile and adult leaves are allowed to develop. If planted in a terrarium or hanging basket the leaves will remain in the juvenile stage. Plants in this genus are toxic if ingested. Exercise caution in the presence of children or pets.

Insects, Diseases, and Other Plant Problems:  Monitor for aphids, mealybugs, spider mites and scale. Common diseases include root rot, stem rot, powdery mildew, and leaf spot. Yellowing of the leaves can occur from overwatering and underwatering. Browning tips result from a lack of humidity. Leggy growth is often caused by inadequate light.
