Although the leaf shape is unique and interesting, the flowers are rather commonplace and do not possess much fragrance. In addition, it is the most rampant Passiflora that I have ever grown, traveling under stretches of concrete to appear in different parts of the garden and even climbing under the house's siding nowhere near the initial planting which was ripped out after only 1 1/2 years in place.

We have a huge caerulea vine growing on lattice work on the west facing side of our house. It flowers a lot and appears to be very hardy here but the strange thing is that the flowers always seem to grow facing away from the sun. The flowers are beautiful and have a wonderful scent but they always appear facing into the plant and not towards the sun. Do others notice this?
