This is a white flowered form of the hardy blue passion flower. P. caerulea is hardy for us in the Lower Mainland, especially against a south facing wall or fence. Plant in well-drained soil that is not too moist or too rich to promote more flowers and less greenery. Edible, but not the most tasty, yellow fruit are produced if pollinators visit. Trick them into visiting, and create a nice plant combination, by growing up an irresistable Buddleia.
