• Environment: Grows on tree trunks (epiphyte) or rocks (lithophyte) under shaded canopy with high humidity and well‑drained, organic‑rich substrate.

Leaves

• Simple, coriaceous blades lanceolate to oblong
• 30–60 cm long, narrowly acute at the base
• With entire margins

Inflorescence (Spadix & Spathe)

• Spathe typically recurved and greenish to pale purple
• Spadix elongated, green tinged with purple or gray‑brown
• Bearing spirally arranged perfect flowers

Growth Habit

• Forms a basal rosette from a short rhizome
• Lacks tubers
• Epiphytic or lithophytic in habit

Light Requirements

• Bright, indirect light
• Avoid direct sun to prevent leaf scorch

Watering & Humidity

• Keep substrate evenly moist, allowing slight surface drying between waterings
• Maintain humidity above 60 percent

Soil & Potting Mix

• A chunky, well‑draining mix of orchid bark, sphagnum moss, and perlite to mimic its natural epiphytic medium

Temperature & Fertilizer

• Ideal temperatures 65–80 °F (18–27 °C)
• Feed monthly with a balanced houseplant fertilizer during the growing season

Division & Cuttings

• Divide clumps at the rhizome
• Root stem cuttings with two nodes in a sand‑peat mix under high humidity

• Fresh seeds germinate in 6–12 weeks under warm, moist, and lightly lit conditions

Typical Issues

• Spider mites, mealybugs. scale, whiteflies, aphids, and thrips

Treatment Recommendations

• Neem oil or insecticidal soap sprays
• Predatory mites for spider mite outbreaks
• Correct overwatering and repot in fresh mix to manage root rot

• The species epithet references Paraguay
• Berries provide food for forest birds and mammals

• Admired for its architectural rosette and subtle inflorescence
• Sought after by collectors of Pachyneurium anthuriums

Wild Population Status

• Populations appear stable with no significant threats reported
