Passiflora racemosa, commonly known as Red Passionflower, is an evergreen perennial vine originating from the Atlantic Forests of Southeastern Brazil. This habitat is characterized by high biodiversity and a warm, humid climate. The vine can reach up to 5 meters (16 feet) in length and features simple or 3-lobed leaves that grow up to 10 cm (4 inches) long. The Red Passionflower is renowned for its striking flowers, which bloom in summer and are about 12 cm (5 inches) in diameter. These blooms are vivid red with purple and white coronas, creating a dramatic display that is highly attractive to pollinators. Following the flowering period, the plant produces oblong green fruits.

The Red Passionflower is a popular ornamental plant due to its spectacular flowers and is often grown under glass in temperate regions to meet its minimum temperature requirement of 13 °C (55 °F). It has been recognized with the Royal Horticultural Society’s Award of Garden Merit, highlighting its value in horticulture. Ideal for trellises, arbors, and walls, it can be used to add vertical interest in gardens. In cultivation, it thrives in full sun to part shade and requires medium to high amounts of water, along with well-draining soil. While it is relatively easy to maintain, it is susceptible to pests such as aphids and spider mites, and in colder climates, it must be protected from frost.CC BY-SA 4.0
