Philodendron sp 'peltatum' ('pastazanum silver')

Philodendron sp. 'Peltatum' – Silver-Veined Collector Aroid with Creeping Growth

Peltatum' Philodendron – Leaf Form, Silver Veining and Creeping Habit

Philodendron sp. 'Peltatum' is a striking, creeping aroid with heart-shaped leaves and bold silver veining. The foliage has a slightly quilted surface and develops a cool-toned sheen under bright light, giving it an almost metallic appearance. Often sold under the name Philodendron pastazanum 'Silver', this undescribed species shows key differences: thinner leaves, wider sinus, and colder-toned veining.

Each leaf unfurls with a soft, matte finish and grows increasingly wide over time, creeping laterally with thick, grounded stems. It's a must-have for collectors of rare Philodendron forms – especially those who love silver-toned foliage and ground-spreading species.

Key features and growth structure

• Leaf shape: Cordate (heart-shaped) with a wide central sinus
• Color: Cool green with pronounced silver-toned venation
• Growth habit: Creeping; stems run horizontally along the substrate
• Leaf size indoors: Mature leaves reach 30 – 50 cm in width
• Surface: Lightly textured with subtle gloss and flattened margins

Botanical background and natural behavior

This plant is an undescribed Philodendron species, likely related to Philodendron pastazanum (described by K. Krause). It is often referred to in trade as 'Philodendron pastazanum silver' due to the leaf shape and creeping growth. Unlike upright Philodendrons, it sends runners horizontally and produces leaves spaced along a grounded stem. It thrives in warm, humid environments with ample substrate space.

Toxic to pets and humans if ingested – always place with care.

Philodendron sp. 'Peltatum' care guide

• Light: Bright, indirect light enhances leaf size and silver tones
• Watering: Keep evenly moist; allow top 2 – 3 cm of soil to dry before rewatering
• Humidity: Prefers 60 – 80%; thrives in high humidity but adapts well
• Temperature: Best kept between 18 – 28 °C
• Soil: Rich, well-draining aroid mix with coco coir, bark, and perlite
• Repotting: Every 1 – 2 years, or when runners reach container edge
• Fertilising: Feed monthly with diluted balanced fertiliser
• Propagation: Stem cuttings with nodes and visible roots – easy to root in moss
• Hydroponics: Can adjust to semi-hydro with leca or pon if humidity stays high
• Pruning: Trim runners to shape or reroot for bushier growth

Common problems and how to fix them

• Drooping leaves: Often due to underwatering or cold stress – check root health
• Yellowing margins: Result of overwatering or poor drainage
• Leaf curl: Common in low humidity or compacted substrate
• Pests (thrips, mealybugs): Wipe leaves often and treat early with neem or insecticidal soap
• Root rot: Prevent by using airy mix and pots with excellent drainage

Helpful tips for best results

Grow this species in a wide pot or long box to give its runners space to spread. Use moss poles laid flat or coir slabs to encourage rooting along the stem. 'Peltatum' benefits from consistent warmth and gentle airflow – avoid soggy conditions. Silver patterning becomes more visible in cooler, filtered light and consistent humidity. Rotate gently to avoid lopsided growth.

Etymology and taxonomic note

Philodendron means “tree lover” in Greek, though this species grows as a terrestrial creeper. The name 'peltatum' refers to a shield-like leaf shape (from Latin pelta, shield), though it remains unofficial in taxonomy. Its similarities to Philodendron pastazanum place it near the same group, but differences in leaf texture, coloration, and vein pattern suggest it may represent a distinct, undescribed species.
