Lardizabala funaria is an evergreen climbing vine native to central and southern Chile. Plants of the World Online accepts this name and treats Lardizabala biternata as a synonym; much of the fruit and horticultural literature therefore uses the older name rather than L. funaria.[1] The vine is known by names including zabala fruit, coguil and coguilera.
Description[edit | edit source]
The plant is a vigorous twiner with ternate to triternate leaves. Its functionally unisexual flowers are dark chocolate-purple; male flowers are borne in drooping spikes, while female flowers are solitary. The fruit is oblong to cylindrical, with a thin peel, pale to white pulp and flattened black seeds.[4] The open fruit study examined material published under the synonym Lardizabala biternata; under the accepted-name treatment above, its measurements are used here as evidence for this taxon rather than as evidence for a separate species.[1][2]
Cultivation[edit | edit source]
Species-specific domestication and cultivation systems remain limited. The native plant grows in Chilean forest and forest-margin settings, from roughly 100 to 1,000 m in the horticultural account; this habitat context points to a supported, moisture-retentive but well-drained site rather than stagnant soil.[2][3]
Soil and water[edit | edit source]
Begin with humus-rich, sandy loam that drains freely while holding organic moisture. A climbing support is essential for a plant described as a vigorous twiner. Avoid persistently waterlogged soil; the available cultivation guidance is a compiled horticultural recommendation, not a controlled species trial.[3]
Sun and humidity[edit | edit source]
Forest-margin conditions suggest protection from severe exposure. The compiled horticultural guidance allows shade or protection through moderate sun, so a grower can start with bright filtered light, good airflow and even moisture, then adjust exposure if the vine shows stress. This is a qualified starting point rather than a verified species-specific light or humidity limit.[3]
Seasonal changes[edit | edit source]
Plan for a warm growing season and protect young growth from spring frost. The horticultural account associates fruiting in cooler climates with a long hot summer, but it does not establish a universal temperature threshold; winter irrigation should be reduced only as the root zone and local weather require, without allowing the vine to dry severely.[3]
Propagation[edit | edit source]
The compiled propagation guidance recommends sowing fresh seed shallowly and also lists 5–10 cm half-ripe heel cuttings as a possible vegetative method. It does not provide a reproducible germination or rooting percentage, treatment comparison or species trial conditions, so these are starting methods rather than guaranteed protocols.[3]
One Tropical Fruit Forum participant proposed cool, damp stratification, possibly in two periods, but described the information as sketchy and conflicting and did not report a successful germination test, plant age or growing location. Treat that report as a lead to test, not as a requirement for the species.[5]
Flowering, fruiting, and harvest[edit | edit source]
The flowers are functionally unisexual, and the open fruit study describes the species as dioecious. A compiled horticultural account uses conflicting monoecious-or-dioecious wording, while the historical description separates male and female flowers. The disagreement means that growers should not assume self-fertility: record sex expression and flowering overlap on established plants before drawing a pollination conclusion.[2][3][4]
The fruit study states that reproductive phenology remains poorly documented. Harvest should therefore be based on observed softening and mature colour on the individual vine rather than on an unsupported calendar schedule. The study sampled ripe fruit collected from climbing vines or soon after natural fall in Chilean forests, but it did not establish a cultivation bearing age or commercial harvest index.[2]
Fruit and uses[edit | edit source]
The fruit is locally eaten and described as sweet and pulpy. In three Chilean population-year samples, 53 fruits from Santa Cruz in 2016, 73 from Valdivia in 2016 and 79 from Valdivia in 2018 averaged 54.2 mm in length and 21.0 g in fresh weight; the full observed ranges were 20.1–83.4 mm and 3.0–44.6 g. The study found substantial variation between sites and years, so these figures describe sampled wild populations rather than a cultivar standard.[2]
The pulp was white, the peel thin, and fruits contained many black seeds—about 48 per fruit on average in the study. Of the tested seeds, 93.1% were classified as viable under the study's assessment, a result that should not be converted into a general nursery germination rate.[2]
Edibility reports and Chilean market references support a traditional food use, but they are not a formal food-safety guarantee. Chemical and toxicological characterization remains incomplete, so unusual quantities, medicinal claims and safety conclusions should not be inferred from the fruit description alone.[2][3][4]
