Great to see this one again. It is the only good passion flower in UK. It won't root from cuttings. Try layering. If it's been a hot summer and you've got fruit with seed, you might try growing it from them. Cut the fruit in half and plant it cut side up (with all the seeds inside) in good compost. Keep warm and moist. Works best when the fruit is just ripe. If you have old seed soak them in bought passion fruit juice for 48 hours. The acid gets them going. Good luck.
