Passiflora ligularis, commonly known as Sweet Granadilla, is an evergreen perennial vine native to montane forests in the Andes from Venezuela to Bolivia, including Panama and Peru. It is a climbing plant that can produce stems up to 5 meters (16 ft) long, which scramble over the ground or clamber into the surrounding vegetation using coiling tendrils. The leaves are abundant, simple, and dark green. The plant is notable for its greenish-white flowers that bloom throughout the year, depending on the climate, with a peak in late winter to early spring. The flowers are fragrant and attractive to pollinators. The fruit is round, orange to yellow with small light markings, and has a hard, slippery outer shell with soft padding inside to protect the seeds. The sweet, aromatic pulp inside the fruit is edible and highly valued for its flavor.

Sweet Granadilla is appreciated for its ornamental flowers, delicious fruit, and as a host plant for butterfly larvae. It is used in gardens for trellises, arbors, and fences, and is also grown commercially for its fruit. In cultivation, it prefers full sun to partial shade, consistent medium watering, and well-draining soil. It can tolerate a range of soil types but thrives in rich, loamy soils. While it is not particularly susceptible to diseases, it can attract pests such as aphids and mealybugs. Gardeners should be aware that in some regions, it can become invasive due to its vigorous growth and should be managed accordingly.CC BY-SA 4.0
