Passion Flower (Passiflora caerulea) is a vigorous, fast-growing climber with exotic, intricate flowers featuring white petals and a striking blue and purple centre, often with a slight fragrance. Flowering from summer into autumn, it adds a dramatic, tropical effect to gardens, thriving on trellises, fences, or pergolas.
