Buy Passiflora caerulea blue passion flower: Climber with large, exotic flowers

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.

Notes on Passiflora caerulea

"This pastel-flowered passion flower, a subtle mixture of warm-blue petals shaded in maroon and green, will straddle a low south-facing roof or porch and produce edible orange fruit"

Wonderful and quick to grow


The plant arrived with three foot long shoots and looking healthy. I planted it in a large pot to the south facing front of the house. Growth was apparent within days. Two months on it is above head height (pot included) and started to stretch out across the front of the house. And we have fruits already. Ideal for novice and impatient gardeners!!!

Wellies on, there's gardening to do



Beautiful happy plant


I am not an experienced gardener but I put this in the ground and it grew to be massive with loads of beautiful flowers within the same year. Very happy!!

Great quality and absolutely beautiful!


Looks fantastic on my pergola. Amazing prolonged display and growth in the first year!




Best supplier


Super products and service




Excellent growth and real value for money.


Bought to grow on a recently built pergola, growth was rapid and extensive, very good value for money.




Rampant climber


I planted it soon after it arrived. It had 3 stems which I fanned out but only one has grown. Having said that, the one stem has climbed voraciously and already covered half our wall. It has survived the two snowfalls well and remained green through the winter. I'm looking forward to seeing it flower this year, I hope. I would welcome suggestions about how to get the other two stems to grow. They are exactly as they were on arrival. Also is there anything I can do to encourage growth lower down where there is less light?




Beautiful flowers, great climber, fast grower!


I use this as a climber along latice work fence and it is perfect. Have used previously a long the front of a lean-to area for cover and colour. Beautiful flower and leaves stay green through wimter. Fast grower Spring through to autumn.

Grew twisted round a 9ft pergola in just 1 year.


Lovely, healthy vigorous climber. Lots of big green leaves throughout the year. Beautiful flowers. Only downside is that the flowers only last a day or two. If you have a shady garden like mine there won't be as many flowers as you'd hope for.




Not sure


As trailer on trellis. Fabulous at first, lots of growth and flowers. Died while flowering.




I would buy this product again


Bought this passiflora to replace one that had succumbed to previous winter . It's now going crazy on the back fence with no frost damage this year .

Passiflora caerulea

4.7 14


I have grown passionflower many years ago and can't remember if it survived our winters I live in the North East of England (Middlesbrough). Occasional snow but usually at higher ground levels. Will this plant survive?


It's difficult to say with any certainty, as each garden will have its own micro climate - and a lot will also depend on how heavy and wet your soil gets in winter.


I've planted a passiflora caerulea near a South facing wall in the South East. However, one neighbour advised that it can run amok and grow in every direction including inside the house, so, I wonder if this is true or if you have any tips on how to prevent that to happen. Many thanks.


Hello, This has an eventual spread of around 10m, so can get pretty big. If you want to keep it smaller, then we advise choosing three to five of the strongest shoots, tying them in to horizontal wires and 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.


Hi, I want to grow passion flower permanently in a pot on a south facing patio. How big a pot will I need? What material is best suited for this (plastic/pottery etc)? Thanks!

Green Dragon

Hello, This climber does get pretty large, so they tend to struggle if they are kept in a pot for too long. If however you are happy to replace it every few years, then I would use the largest pot you can find (it wont matter too much if it is plastic or terracotta) and make sure it is kept really well fed and watered.


Is this suitable for an exposed coastal garden?


Hello, No, I'm afraid it is not suitable for a coastal garden, however the honeysuckles tend to thrive - please click on the following link to go straight to them.


My passion flower looks like it is dying from the bottom of the plant up. The leaves at the top of the plant are healthy and there are healthy shoots developing from the middle of the plant up. However the leaves at the bottom are yellowing and dying off. It is a young plant bought springtime, started off in my greenhouse before hardening off and planting out.

total novice/sometimes numpty

Hello, It is quite normal for these climbers to lose their older, lower leaves as they tend to develop a woody stem over time. Therefore I would not be too concerned as it is a natural part of their life cycle, but you may b able to encourage more lateral branching by pinching back the growing tips.


I bought the Passiflora caerulea early November last year and planted it straight away with a good bark mulch for winter protection. It's been a fairly mild winter here in the North East, but while everything else in the garden is growing strongly, or at least showing buds, there is no sign of any growth on the Passion Flower We are 1000' up on the east side of the Pennines, but even the hardy Fuschias are budding out well by now Is it still too early for the Passion Flower? How long should I wait to expect any signs of growth? I would hate to pull it out and then see happy live shoots showing lower down!


Hello, In spring, these plants do sometimes take their time to get going, so you may just need to give them a bit more time. Having said that, they are not fully hardy, so it may have succumbed to the cold weather. You can check to see if it is still alive by gently scraping your fingernail along the stem. If it is green just below the bark, then it is still alive.


Hello... Im looking to plant a climber in my front garden but I live in a town house with only a narrow driveway to the garage at the front so I would need to plant a climber in a container... I was looking into either a Ivy (Boston of Virginia) of a clematis; however is it possible to keep a climber and let it successfully establish in a pot long-term? Thanks.


Hello, It really depends on how big the container is. Most climbers get quite big, so they do also develop an extensive root system. If their roots are restricted in a small pot, they will be much less vigorous and will be more prone to pests and diseases. Ideally a better solution would be to lift a couple of paving slabs and plant them straight into the ground.


Problems with my Passionfruit clmber after cutting back, and an Acer that I moved? Hi Crocus I've recently had my garden designed and am very pleased with the results, (plus many good Crocus plants). Unfortunately, my gardener had to cut back my Passionfruit climber which is about 7 years old. Whilst the other climbers (Honeysuckle / Jasmine) are starting to bud and grow back the Passionflower doesn't seem to be, - is there anything I can do to encourage growth? Also I have an Acer, (about 5 years old), which was frazzled by the sun last summer when I moved it from it's semi-shaded pot, into the ground in more sun. Now there are only a couple of buds that are appearing on the ends of some of the old stems, - should I cut back the ones that don't appear to be shooting, or again is there something I can do to encourage growth? Thanks Vickie

Vickie Kirk

Hello Vickie, Passionfruits often don't recover from being cut back really hard, but the only thing you can do now is wait and see if it rallies around. I would be reluctant to feed it or try to push it, but do make sure it is watered when the soil gets reasonably dry. If however there are still no signs of growth by early June, then I doubt it will come good, so it may need to be replaced. As for the Acer, I would be patient and see if it does start the shoot from the other branches, but again by early June you will be able to see clearly if certain stems are dead and if they need to be cut out. Same rules apply here as to feeding and watering. I hope this helps. Helen Plant Doctor

Passiflora not flowering Hello, We have a Passion Flower climber that we have had approx 3 years, it has grown quite well but as yet it has not produced any flowers. We pruned it right back last year but still no flowers, please can you give us some advice? Thanks

Helen Williams

Hello There, There are a number of reasons why plants don't flower including too much shade, not enough water or nutrients, or pruning at the wrong time of the year. It can also be caused by the plant putting on new root growth instead of focusing its energies on producing flowers. I am not really sure why yours has not produced buds, but you can often give them a bit of a push by feeding with a high potash fertiliser. I hope this helps, Helen Plant Doctor

Passion Flower I am a little worried about my passion flower. The leaves are really yellow - mainly between the veins and now it is developing brown spots. Do you know what may be causing this? Many thanks Juliet

Hello Juliet, It sounds as though your plant is suffering from a magnesium deficiency. Magnesium is easily leached from the soil after heavy rain. Deficiencies can also be caused by using too much potash (which is used to encourage flowers to form), or if the plants are grown in acidic soils. I would advise that you spray it with Epsom Salts as a foliar spray, diluted at a rate of 200g per 10 litres of water with a few drops of washing up liquid added in. You will probably need to repeat this several times at weekly intervals before the plant starts to recover. Helen Plant Doctor
