Hardy Passiflora (made in Italy)

Ditto for mollissima and vitifolia! The only species I can get to flower from a Spring sowing is foetida...

 

I was thinking more of plants overwintering outside, but I must agree, only ever got cerulea and foetida to flower first year from seed.

 

Overwintering, well, that'll be the challenge
I never know from one year to the next what to expect by way of temperatures, so stuff has to survive anything from -4C to -17C

 

@sal73 - how hardy will the P.manta and "Caprice" be?

 

Hi guys, I have to learn how insert pics in your forum. In the mean time, you can watch some of my plants here.
I know you have winter just a little bit better than in Italy. I’m sure you can cultivate P. ‘Fata Confetto’, P. naviculata, P. ‘Guglielmo Betto’, directly in the garden.

They use to lost all during the winter, but in the late spring the plants grow up from the roots and soon they bloom. You have to use plants from seeds born since at least one year, well rooted cuttings (since at least 6 months more and less). If they are too young, they’ll die during the winter.

 

P. 'Manta' is not wery hard, 5/7 °c.
P. 'Caprice' in Rome resisted 0°c for some days

 

Thanks!!
So of my five Passiflora, four will need to come indoors for the winter then!

 

which are the others?

 

P.alata
P.antioquensis
"Amethyst" (should be hardy that one?)

 

P. alata resists 5°
P. antioquiensis 1°
P, Amethyst 3 °

...more and less ;-)

 

It will have to take its chances outdoors as I planted it out this year!

 

There are some Passifloras that in Italy are very difficult to grow up. They are the subgenus Tacsonia. See P. mollissima, P. antioquiensis, P. ‘Mission Dolores’ ecc. ecc. They have many problems with our sun, but they are frost resistant if you keep them out of the rainfall in winter. John Vanderplank, in his book (Passionflower), suggest to plant them directly in the garden and to make a plastic cover to protect the plants during the winter.

Passiflora 'Exoniensis'


Passiflora mollissima



Passiflora 'Mission Dolores'



The cover (some ex.)




(you need a plastic without holes)

 

Stefy , really nice variety and well worth to covering them , can you give us more information on the soil ph or what soild they prefer?

Longk , have you got a cearulea???? did you ever thing to try to make hybrid with your passiflora?
my p.alata actually died after a week of -1c in the cold greenhouse , really doesn`t like cold , overall thing about an hybrid .

I hope Stefy will show us how to do it

 

So ... the passion flowers prefer slightly acidic soils. The best soil is the one with sand and pumice stone (3/6mm. for big plants, 2/5mm. for young cuttings and seedlings). The main problem that causes the death of plants is the excess moisture around the roots and collar. You rarely lose plants for poor wetting.


Passiflora alata and all those of the subgenus quadrangulares, I find that they are really difficult to grow. For these you have to use even more inert in the soil and measure out the water. The general rule in the best months is a good irrigation (wetting all the soil in the pot) but wait it dries completely before repeating. During the winter the better things is not irrigate if frost, and during the winter irrigate with some water from the bottom of the pots (using a flower pot saucer) only to prevent the plant dried.

 

Are you saying that P.antioquensis likes a little shade Stefy?
