Plant details

This popular passion flower has creamy-white flowers with purple-blue zoned coronas. The attractive foliage is 10cm (4in) across, glossy green and very deeply lobed. Plants make rapid annual growth each year as this clings with tendrils, plants won't damage brickwork or fences but need suitable supports to grow on. Passion flower is in bloom from mid- to late summer and, after a warm summer, it is not unusual to find large orange-yellow fruits forming. These can be left on the plants for decoration. They are edible but do not have an outstanding flavour. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).

Should my passion flowers have growth on them by now? I had them last year and put them into pots as we were altering the border. Now it is done I have planted them (2) and do not see any sign of life yet. They were beautiful last year. Help!


Something is eating my young passion flower, I think it my be ants. I've grown passion flowers before with no trouble. Any ideas?


I have the same problem with a mystery muncher. Thought it might be earwigs so set pots with hay as traps but no result.


My passion flower is growing up a wall and I have noticed snails have crawled up to eat it, might be the same thing.
Love passion flowers though, a lovely plant to have in your garden if you can and it has been a fantastic grower this year
