This climber is semi-evergreen, so it can lose some of its leaves in winter. In colder regions or more exposed gardens, it may lose them all, but then fresh new foliage appears again in spring.

  • Position: full sun or partial shade
  • Soil: moderately fertile, moist, well-drained soil
  • Rate of growth: fast-growing
  • Flowering period: July to September
  • Hardiness: frost hardy (will need winter protection in cold areas)

    A really exotic-looking plant, with large white flowers and central filaments of purple, blue and white from July to September, followed by egg-shaped, orange-yellow fruit. The leaves are pretty, too; deeply lobed, dark green and glossy. This blue passion flower is a vigorous, trouble-free climber that thrives in hot summers and will quickly cover a sunny wall or fence. Ideal for a tropical planting scheme, it grows best at the base of a sheltered wall in full sun, although it will tolerate some shade. The fruit are edible when full ripe, but not very tasty!

  • Garden care: Choose three to five of the strongest shoots, tying them in to horizontal wires. Once the plant is established, cut back the flowered shoots immediately after flowering to within two or three buds of the permanent framework of the plant. In spring remove dead, misplaced or overcrowded stems.
  • Harmful if eaten
