Passiflora caerulea the blue passionflower is the passionflower that brought the extraordinary beauty of the Passifloraceae to European gardens: the hardiest of the genus, capable of surviving frosts that would kill its tropical relatives, its elaborately banded corona and luminous white petals making it one of the most recognisable ornamental climbers in gardens from Portugal to southern England.
