What Is a Passiflora Alata?

The Passiflora Alata is a climbing, fruit-bearing vine originating from South America. The gorgeous cascade of evergreen leaves, attractively scented red flowers, and delicious fruits make this plant quite popular. Attractive to many pollinators, such as bees, butterflies, and birds, the Passiflora Alata is beloved by many gardeners worldwide.

Passiflora Alata Care

The Passiflora Alata is quite easy to grow and does not require any special care. The quick-growing nature of this climbing plant creates a natural rambling charm perfect for many gardens. Here’s how to do it properly:

– Water

The Passiflora Alata loves abundant watering during its active growing seasons. Abundant watering encourages flowers, which then coax fruits to develop. The flowering and fruiting period requires regular and deep watering. Watering should not just be focused on the plant base but also around the plant where the roots may spread out.

The active growing season of the plant is crucial in terms of watering amount and frequency. Dry soil conditions are often the cause of wilted premature fruits that eventually drop.

Cooler Season Requirements

In cooler seasons, the watering amount and frequency should be reduced. The Passiflora Alata does not tolerate frost well, so keeping the plant safe from freezing is ideal. The plant can tolerate temperatures no less than 45 F, and gardeners are encouraged to ensure a comfortable winter temperature for the plant to survive the winter.

Cooler Season Requirements in Passiflora

– Light

The Passiflora Alata prefers to grow in areas where full sun exposure is present. The longer it is exposed to the sun, the more foliage, flowers, and fruits are produced. Locations in the east or south are ideal for the Passiflora Alata as it can absorb the most light without any harsh lighting conditions.

The Passiflora Alata can grow in partial shade, although too much shade will not produce flowers or fruits.

In indoor cultivation conditions, the Passiflora Alata will adapt well and thrive with grow lights.

– Soil

The Passiflora Alata prefers rich, moist soil that drains quickly. Growing on sandy embankments in its local habitat, the plant’s roots have adapted to well-draining soils that are rich in humus. The plant does not tolerate soils that are very acidic or with high alkaline content; soil that is neutral is the most appropriate planting material.

In pots, the Passiflora Alata can grow well in loamy compost mixed with fertile, quick-draining soil that is slightly sandy.


Repot Passiflora Alata plants in the springtime, when it is about to go into its active growth periods. Slightly crowded root conditions in pots tend to encourage the plant to produce more flowers, so repotting should not be done often.

– Temperature

The Passiflora Alata prefers warm temperatures but can tolerate cooler temperatures as long as they do not fall below 41 F. They are normally grown outdoors in temperate regions where the temperature is tolerable. In warmer regions, the temperature is not as crucial since the Passiflora Alata is a warmth-loving plant.

In temperate regions, the Passiflora Alata is often grown indoors, where the temperature and light requirements can be far more easily controlled.

– Fertilizer

Passiflora Alata plants are heavy feeders, and they would do well with regular fertilization to enhance their flowering and fruiting performance. Fertilizers with lower ratios of nitrogen and potassium are ideal for preventing root burns and fruit drops.

Depending on the size of the plant, fertilization should be adjusted and in proportion to the plant’s overall bulk.

Inorganic and organic fertilizers may be used to boost the plant’s flowering and fruiting capabilities.

– Rest Period

The Passiflora Alata is a half-hardy climbing vine, which means it prefers to have protection from harsh cold winters. In areas where the climates have cold or wintry conditions, growing the plant is preferably in pots where they can be taken indoors to overwinter.

While they can tolerate cooler temperatures, the Passiflora Alata does not tolerate cold. When exposed to cold temperatures, the plant usually suffers frostbite and does not survive the winter.


The Passiflora Alata is propagated in different ways.

When propagated through seeds, it is recommended to sow the seeds once it is ripe. The pulp increases germination, and the seedlings may be transplanted once bigger.

Planting more Passiflora alata

Cuttings of young shoots are another method to propagate the Passiflora Alata. Cut at the nodes; the cuttings are ideally placed in a neutral compost mix, although some success has been reported when mixed with sand.

Fully mature wood cuttings can also produce great results, with a higher percentage of success than using young shoot cuttings.

Grafting is also another successful method of Passiflora Alata propagation, with fewer risks.

– Name Origins

The Passiflora Alata derives its name from the Latin words “passio,” which means passion, and “flos,” which means flower. The plant family is collectively known as Passifloraceae and is more commonly known as passionflowers. The fruits that are produced from this family are called passion fruits.

Other Names

The common name passionflower is sometimes referred to as “the flower of the Passion.” This is due to the symbolic elements of the flower that are closely tied to the Christian Passion instruments.

Other common names include Fragrant Grenadilla, Maracuja de Refresco, and Ouvaca.

The epithet “alata” is Latin for “winged,” which refers to the four-winged stems of the flower.

– Size

The Passiflora Alata can reach a height of 20 feet, as it is an evergreen climbing vine. The four-stemmed vine is a moderately quick grower, so regular pruning is recommended. Pruning increases the flowering and fruiting production of the plant, and pruning makes the flowers and fruits more accessible for picking.

For warmer climates, pruning is recommended immediately after harvesting the fruits. In temperate regions with cold seasons, springtime is the ideal period to begin pruning.

Passiflora Alata vines that are soft and bent are often most likely to produce flowers and fruits, so any pruning should not be severely extensive.

– Leaves

The Passiflora Alata leaf is oval, typically four to six inches long and around four inches wide. The large closed-edged green leaves are lobed and oval that remain lush throughout the active growing season.

Many Brazilians use the leaves of the plant for diaphoretic, anthelmintic, and anti-hysteric purposes.

The climbing and vining habit of the Passiflora Alata plant creates tendrils that attach to other plants or structures for support. The tendrils can be trained to vine or climb onto plant support frames or allowed to ramble on naturally.

– Roots

The Passiflora Alata has a shallow root system in contrast to this large foliage growth. The Passiflora Alata leaves and roots may contain “passiflorina,” a substance that can act as a tranquilizer. Because of this claim, the passionflower, its leaves, and its roots may sometimes be found in herbal teas that claim to promote calm and better sleep.

– Flowers

The Passiflora Alata displays impressive crimson flowers that are quite fragrant in the late summer to late fall. The intensely scarlet, curved petals with their ringed purple and white filaments are dramatic and awe-inspiring. The fragrance is equally breathtaking, with a combination of tart and sweet aromas that hint at the taste of its fruit.

The Passiflora Alata is a popular attraction for many bees, butterflies, and birds due to its color, aroma, and nectar. The pollination of the flowers encourages the fruits to develop. The flowers and the fruits tend to develop on the softer, drooping vines of the plant.

– Fruits

Passionfruit is large and golden yellow, with a mildly sweet taste and flavor. The passionfruit is rich in vitamin C and normally made into juices, jams, smoothies, and even raw. Aside from vitamin C, the passionfruit is also a good source of vitamin A, folate, phosphorus, magnesium, and potassium.

Passiflora alata Fruits

Once opened, the fruit’s cavity is filled with edible white seeds covered by pulpy yellow gelatinous flesh. Other culinary uses for the seeds include incorporating sweet pulpy seeds into ice creams, pies, cakes, and fruit salads. Some cooks include the Passiflora Alata seeds into savory dishes, while others add them as toppings to desserts.

– Habitat

The Passiflora Alata is native to South America, in countries such as Argentina, Brazil, Bolivia, Paraguay, and Peru. In its native regions, the plant thrives in sandy dikes and embankments, as well as in rainforests. The Passiflora Alata thrives in lowland tropical and subtropical environments, making the passionfruit highly valued in countries like Brazil.
