Passiflora tenuifila, commonly known as Slender Passionflower or Slender-stem Passionflower, is a fast-growing vine native to the cerrado and Atlantic forest biomes in South America, including Brazil, Paraguay, and Argentina. It typically reaches a height of 6-10 feet (1.8-3 meters) and a width of 3-6 feet (0.9-1.8 meters). This species is characterized by its slender stems and lobed leaves, with distinctive purple or white flowers that are notably showy and bloom in the summer. The flowers are followed by small, oval fruits that may be of interest in the garden.

Slender Passionflower is valued for its rapid growth and ornamental flowers, making it a popular choice for trellises, arbors, and fences in tropical and subtropical gardens. It can also be grown in containers where it can be overwintered indoors in cooler climates. While it thrives in full sun to part shade, it prefers medium to fast-draining soils such as clay, loam, or sandy types, and requires regular watering to maintain moderate soil moisture. Gardeners should be aware that, although not common, it can be susceptible to pests such as spider mites and whiteflies, especially when grown indoors or in greenhouse conditions.CC BY-SA 4.0
