Passiflora caerulea

Passiflora caerulea, the blue passion flower, is a vigorous tendril-climbing vine prized for its striking summer blooms: white petals crowned by blue to purple filaments. Its dark green, palmately lobed leaves clothe fences, walls and pergolas, and it thrives in full sun or light shade in moist but well-drained, moderately fertile soil. This climber requires a suitable support to establish and grow. Ultimately, when trained, it can reach about 12m in height with a spread of roughly 4m. Semi-evergreen in mild areas (deciduous in colder spells), it holds the RHS Award of Garden Merit.

This climbing plant has been trained onto a supporting frame to create a neat, well-shaped specimen that is ready for planting. As it grows, new shoots can be guided and secured to continue developing its natural shape.

To help give a clear sense of scale, the stone wall shown in our photos measures approximately 265cm in height. We also use familiar garden tools as visual references: a digging fork (110cm tall) and a hand fork (30cm tall). These are included purely as size guides to help you better judge proportions when viewing the images.
