About Passiflora allardii
Passiflora allardii, known as Cambridge-Passionsblume, is a vigorous and ornamental passion flower hybrid resulting from the cross between P. caerulea and P. quadrangularis. Its large flowers, up to 10-12 cm in diameter, feature white or pale lavender petals and a corona of violet and white filaments, emitting a soft fragrance. It is ideal for covering pergolas, fences, or walls, creating a spectacular visual impact in temperate gardens or as a bright indoor plant in colder climates.
Native range
Horticultural hybrid, has no natural native distribution
Care tips
It requires full sun or bright partial shade for abundant flowering and optimal development. Watering should be regular during the growing season, keeping the substrate moist but not waterlogged, and reduced in winter. It prefers well-drained, fertile soil with a slightly acidic to neutral pH. A common mistake is lack of pruning: prune it annually in spring to encourage denser flowering and control its vigorous growth.
