Notes
Blue passion flower (Passiflora caerulea) is a vine for borders, containers, cottage gardens, and privacy screens. It is hardy to USDA zone 7, or down to 0°F (-18°C). This plant likes full or part sun and average to moist soil of most types. It climbs fast and bears blue blooms in summer and again in autumn, which draw butterflies and bees. It sits low on the menu for deer and rabbits. Give it a trellis or fence to climb.
Pairs well with Jasmine, Silver sage, and Catnip.
