Description
Carica lanceolata is a small, fast-growing, evergreen to semi-evergreen fruiting tree closely related to the common papaya but adapted to cooler high-altitude climates. Typically reaching 3 to 6 meters in height, it develops a slender trunk topped with large, deeply lobed leaves. The tree produces elongated, aromatic fruits with yellow to orange flesh that offer a tangy, refreshing flavor, well suited for fresh eating, preserves, and juices. Native to the Andean highlands of South America, it thrives in full sun and fertile, well-drained soil, showing greater tolerance to cool temperatures than tropical papaya species. It is valued for its ornamental foliage, nutritional fruit, and suitability for subtropical and upland cultivation.
Germination Guide
🌍 Andean highlands of Bolivia and Argentina at elevations between 1200-3300m (3900-10,800 ft), in dry scrubland
Moderate
Carica lanceolata is an extremely rare, high-altitude papaya species native to the Andean highlands of Bolivia and Argentina, producing distinctive pear-shaped striped fruits. This evergreen to semi-evergreen small tree is adapted to cooler, high-elevation climates and exhibits remarkable frost tolerance compared to tropical papaya species. Seeds require warm temperatures and high humidity with excellent drainage; gibberellic acid treatment significantly enhances germination success.

Substrate & Container
Recommended substrate
High-quality, light, porous substrate that is well-drained and pathogen-free. Avoid overly rich substrate to prevent fungal issues in confined seed trays.
Recommended container
Plastic pot with transparent cover or glass plate to maintain humidity and allow light penetration while enabling daily aeration
Growing Tips
Open pot daily for air exchange to prevent fungal issues in confined conditions and monitor substrate moisture. Seeds require light for optimal germination, so do not bury deeply; maintain slightly humid conditions throughout germination. Ensure temperatures remain between 22-28°C with 25°C being ideal. After germination occurs (typically 10-30 days), transfer seedlings to individual pots to prevent damping-off disease. Acclimate young plants gradually before transplanting to final location by exposing them to increasing periods of air circulation and moderate light. Watch for fungal development, which thrives in high-humidity confined spaces.
