Passiflora quadrangularis – the giant passion fruit for gardens and greenhouses

Passiflora quadrangularis , commonly known as giant passionflower or maracuja, is a tropical climber prized for its enormous flowers and impressive edible fruits. This exotic climber is perfect for gardeners who want to combine ornamental value and fruit production and create a tropical ambiance in their garden or greenhouse.

The fruits of Passiflora quadrangularis, also known as giant granadilla, are large, yellow-green, and aromatic, and rich in vitamin C. The plant also attracts pollinators such as bees, bumblebees, and butterflies, which contributes to biodiversity in your garden.

Description and growth habit – impressive and exotic

Passiflora quadrangularis is a fast-growing, vining climber that can climb tall structures with sturdy tendrils, up to 10 meters. Its foliage consists of deeply incised, dark green leaves, which give it a lush, tropical appearance.

The flowers are enormous and striking, with white sepals, purple filaments, and a contrasting center. They bloom from summer to early autumn and are highly decorative against pergolas, fences, or in greenhouses. After flowering, gigantic fruits develop, often reaching over 20 cm in length and with an impressive, exotic appearance.

Cultivation and care – tropical conditions required

Passiflora quadrangularis grows best in warm, sunny climates or in a greenhouse in cooler conditions. Important growing tips:

• Location: Full sun for optimal flowering and fruit development.

• Soil: Well-drained, nutritious and slightly acidic to neutral.

• Watering: Water regularly; the roots should not remain wet for long periods of time.

• Support: Climbing growth requires strong pergolas, trellises or fences.

• Winter protection: Frost sensitive; in cold climates overwinter indoors or sheltered with mulch.

Regular pruning helps control growth and encourages both flowering and fruit production.

Application and ornamental value

Passiflora quadrangularis offers both ornamental value and edible yield and can be used in various ways:

• Pergolas and trellises – create a tropical and lush look.

• Fences and fences – natural separation with ornamental value and gigantic fruits.

• Greenhouse or large pots – suitable for cooler climates or balcony planting.

• Biodiversity – attracts pollinators such as bees and butterflies.

• Fruit production – edible giant fruits for fresh consumption or processing into juices, desserts and jams.

The combination of enormous flowers and impressive fruits makes Passiflora quadrangularis a special eye-catcher in any garden or greenhouse.
