Hello Doreen,
Thank you for your question about your Passion Flower plant. The most common passion flower in cultivation is the Blue Passion Flower; Passiflora caerulea.
It is fine to plant your Passion flower in average, moderately nutritious garden soil, it should be reasonably drained but also hold on to some moisture. Ideally, plant it against a south or west facing wall. I would avoid an east facing wall because such a site will have early morning sun with the potential for a rapid thaw from a late frost; this could damage the developing flower buds.
Passiflora caerulea flowers all summer and into autumn. It is a slightly tender plant and will cope with frost down to –5C.
I would feed your Passion flower once per fortnight during spring, maybe with a tomato food that will encourage lots of flower development. Rig up some kind of support on the wall, the passion flower will need something to grab on to with it’s wispy modified leaves called tendrils.
Hope I have been of some help,
