The plant gets its name from the prominent wings along its stems. It can grow to be quite large, with vines stretching up to several meters long, using tendrils to cling and climb on surrounding vegetation. The leaves are simple and alternate, shaped like elongated ovals or ellipses, typically measuring 10 - 15 cm in length. They have a pointed tip and a rounded base, with a smooth margin, and a tendril sprouts from the leaf axils.

The flowers of Passiflora alata are truly a sight to behold. They are large, boasting a diameter of 10 - 12 cm. The five sepals are petal - like, with a deep red - purple hue on the inner side and a greenish - tint on the outer. Complementing them are five equally stunning purple petals. The most eye - catching part, however, is the elaborate, filamentous corona, which displays an attractive pattern of alternating purple and white. These unique flowers not only add a touch of elegance to the environment but also play a crucial role in attracting pollinators.

In Brazil, the Winged - stem Passionflower has historical significance as it was included in the first edition of the Brazilian Pharmacopoeia in 1929 for its medicinal properties. Some believe it has effects such as soothing the throat and promoting relaxation. In terms of cultivation, it thrives in warm, tropical climates with well - drained soil.
