Passiflora kermesina, commonly known as Red Passion Flower, is an evergreen or semi-deciduous perennial vine native to the Atlantic Forest biome in southeastern Brazil, particularly thriving in forest edges and clearings. It can grow to a height of 17-26 feet (5-8 meters) and a width of 10-15 feet (3-4.6 meters). The vine is characterized by its complex, showy flowers with a prominent central structure surrounded by vibrant red petals and sepals, blooming primarily in the summer months. The foliage is deep green, and the plant may produce oval, yellow-orange fruit if pollinated.

Red Passion Flower is valued for its striking flowers and rapid growth, making it a popular choice for trellises, arbors, and fences in tropical and subtropical gardens. It is also used as a houseplant in cooler climates. While it prefers full sun to part shade, it requires protection from intense afternoon sun in hotter regions. The vine thrives in well-drained soil and benefits from regular watering, though it is somewhat drought-tolerant once established. It is not known for major disease problems, but spider mites and whiteflies can be an issue in dry, indoor environments. Pruning can be done to maintain shape and promote more vigorous growth.CC BY-SA 4.0
