Passiflora quadrangularis | ‘Giant Granadilla’ | 25 seeds

Passiflora quadrangularis is a useful and spectacular flowering and fruit-bearing vine of the Passifloraceae family. Native to the Neotropics in USDA Hardiness Zones 10-11, this popular climbing perennial produces the largest fruit of any known Passiflora species, causing it be much grown both commercially and as an ornamental.

Commonly known by names such as ‘Badea’, ‘Barbadine’, ‘Giant Granadilla’, ‘Giant Tumbo’, ‘Grenadine’, ‘Passion Flower’ and ‘Passion Vine’, quadrangularis grows as a straggly evergreen vine up to approximately twelve metres or so in height. Smooth, ovoid to elongated green leaves are profuse, while the tendrilled, red-purple-lavender-white flowers bloom repeatedly throughout much of the year, giving off a beautiful scent in the process. As mentioned above, the tasty, juicy fruit is large and oblong in shape. The roots – and perhaps other parts – of the plant are moderately toxic. On the commercial market, Passiflora quadrangularis is sometimes sold mislabelled as the related hybrid Passiflora x decaisneana.

As with many Passiflora species, the fruit is used for eating raw, in cooking and for its juice. Some indigenous traditions recommend drinking a tea brewed from the leaves to treat diabetes and high blood pressure. It’s also a popular ornamental, which has garnered the British Royal Horticultural Society’s Award of Garden Merit.

Quadrangularis is fairly easy to grow from seed or cutting, although will need to be grown indoors or under glass if you’re not located in a suitable climate zone, as even very light frosts can totally kill it. A minimum temperature of 15°C or above is highly recommended! Grow in full sun to partial shade in well-drained, neutral to acidic soil. Space the plants at least a metre apart so that they have enough room to reach their full potential – and watch out for it swamping all of the available space over time! Passiflora has a high drought tolerance and can become an ‘agricultural weed’ if allowed to spread unhindered. It’s therefore advisable to regularly prune the plant, as well as to train the vines onto fences or trellis’ to limit its growth.
