Lapoanum' Philodendron – Rare Leaf Morphology, Collector Status and Climbing Growth

Philodendron sp. nov. lapoanum is a newly described species by botanist Thomas Croat, known for its elongated, paddle-like leaves and elegant venation. This species shows a clean, glossy green surface with a refined, narrow midrib and subtle lateral veins, giving it a sleek, minimalist look. The foliage remains lance-shaped even in maturity, with gently curved margins and a consistent upright form.

As a climbing species, lapoanum thrives when given vertical support and stable warmth. It’s rarely found in cultivation and offers a fresh take for collectors seeking out lesser-known Philodendron species with sculptural appeal and steady, manageable growth.

Foliage traits and growth behavior

• Leaf shape: Elongated lanceolate to narrowly elliptical, tapering at both ends
• Surface: Glossy green, slightly leathery with fine parallel venation
• Growth type: Moderate-speed climber with long internodes and aerial roots
• Indoor size: Can reach 1.5 – 2 m with support
• Texture: Smooth and structured, strong midrib and upright leaf stance

Natural habitat and scientific background

Philodendron lapoanum was described by Dr. Thomas Croat and originates from tropical forests in the Chocó region of Colombia. It grows epiphytically, climbing trees in warm, humid rainforest conditions with filtered light and consistent rainfall. Its morphology distinguishes it from other lanceolate species by the elegant venation and glossy sheen. The species name ‘lapoanum’ refers to the locality of Lapo, near where the type specimen was collected. Like most aroids, it is toxic if ingested – keep out of reach of pets and children.

Philodendron lapoanum care instructions

• Light: Bright, filtered light helps maintain gloss and compact internodes
• Watering: Let top 2 – 3 cm of substrate dry before watering again
• Humidity: Performs best at 60 – 80%; stable conditions preferred
• Temperature: Ideal range 18 – 28 °C – avoid drafts or cold exposure
• Soil: Well-draining aroid mix with bark, coir, perlite, and leaf compost
• Repotting: Every 1 – 2 years, or when rootbound
• Fertilising: Monthly during active growth with diluted liquid fertiliser
• Propagation: Stem cuttings with at least one node and aerial root
• Hydroponics: Adapts to semi-hydro in high humidity environments
• Pruning: Cut long runners or remove older leaves as needed

Common issues and how to address them

• Leaf yellowing: Usually linked to overwatering or poor drainage
• Slow growth: Normal in low light – increase brightness or add humidity
• Pale foliage: May indicate nutrient deficiency or compacted roots
• Pests (thrips, mites): Monitor undersides; treat with neem oil or insecticidal soap
• Drooping vines: Provide vertical support for climbing and healthier form

Additional tips for thriving growth

Use a moss pole or coir support to train Philodendron lapoanum vertically. Its growth remains tidy and minimal when given structure and space. Rotate regularly for even growth and clean leaves gently to preserve the glossy surface. This species prefers consistency – once placed in the right environment, it settles in and grows steadily without fuss.

Etymology and scientific description

The genus name Philodendron comes from Greek – “philo” (love) and “dendron” (tree), referencing the climbing nature of the plant. The specific epithet 'lapoanum' was given by Dr. Thomas Croat in honor of the region where the plant was first identified. The species is considered newly described (sp. nov.), and only recently available to collectors.
