The passion flower (Passiflora caerulea) is one of the most exotic-looking climbers you can grow outdoors in Britain, yet it is surprisingly tough. Often sold simply as the blue pa ssion flower, this passiflora caerulea earns its RHS Award of Garden Merit for the sheer drama of its blooms: flat, white-petalled stars topped with an intricate corona of blue, white and deep purple filaments, each one looking almost too elaborate to be real. They appear in a long succession from midsummer well into autumn, and in warm seasons are followed by egg-shaped orange fruits.Why gardeners love it Genuinely hardy, the toughest passion flower for UK gardens (RHS H4) Long flowering from July to October, often dozens of blooms at once Vigorous, self-clinging by tendrils, perfect for covering walls and fences fast A magnet for bees and listed on the RHS Plants for Pollinators As a passion flower plant it is a fast, twining climber that scrambles up to 4 to 8 metres using its curling tendrils, so it is ideal for clothing a sunny wall, trellis, pergola or fence in a single season. Its semi-evergreen, deeply lobed leaves give a lush, almost tropical backdrop to the flowers.For the best results, plant in full sun in a warm, sheltered position, ideally against a south or west-facing support.

A spring prune keeps it tidy and within bounds, and a winter mulch over the roots safeguards it in colder gardens, where top growth may die back before reshooting from the base.Whether you are looking for passion flower for sale to cover an awkward fence or want a true talking-point climber, this is a rewarding, long-flowering choice.
