Passiflora in the garden as annuals

I am curious. Are you growing some Passiflora as annuals in the garden?
Which species or variety do you use?
Do you sow them directly in place or do you start them indoors?
Do you buy plants and let them die with the Fall?

I do not, but I would be interested in trying. I am in a USDA zone 6. Summers could be awfully wet or desperately dry: no rule about it.

I know this is very little help... but I could easily grow P. foetida as an annual. Most of our seeds of multiple varieties started in late winter have been blooming for about a month, and should continue for another month. I am just not sure if you would get enough sun in zone 6 for them to bloom.

Something else we have done for years with plants that are not frost hardy, is take cuttings in fall, grow the small plants indoors for winter, then plant out in spring, to repeat each year. We have done this successfully with Pentas, Irisine, Solenostemon, and others, though I see no reason why you could not do it with Passifloras. Obviously, you would need to choose those that could easily bloom at a small size.

All of this, I'm sure you have already thought of...

And there is always P. gracilis!

Good luck,

Thank you Eric,

For me, except for some species of subgenus Decaloba, cuttings do not root in short days unless I provide extra light. I mean even in the greenhouse.

So I will look for seeds of the species of section Dysosmia. some are really nice in flower and fruits.

Is P. gracilis still in cultivation? I'd love seeds of it. It may not be spectacular, but it would grow quickly.

As for the sun in Summer, in September we were still in the 80s and 90s. No problem!

Dear Christian,

I can tell you that I grow 99% of me Passiflora as annuals here in an equivalent of USDA Zone 6. To preserve my collection I just take cuttings in September and overwinter the young plants on the windowsill. Then they go into the ground in early May of next year and the cycle repeats.
I grow different varieties of:
Incarnata
Caerulea
Tucumanensis
Edulis
+ hybrids of above species + a dozen of different hybrids

Good growing

I am a zone 6 as well. Have you tried lutea or incarnata with a good mulching, they may turn out to be perennials.

Hi Julie, I am also in Maryland and I have P. lutea, P. incarnata, P. incarnata (white) & P. caerulea 'Concordia' in the garden. After 20 years, they are doing well. I was looking for more variety. I think I will start P. foetida indoor and plant them in the garden in May. I'll let you know how it does.

I am up in Western Maryland. But your growing them actually excites me, as I wasn't really sure it was possible. What part of Maryland are you from? I might even have to try the caerulea.
I do know that my foetidas, pura vida purple, lady margaret, edulis, incarnata, kermesina, kewensis, Holosericea, Choconiana, mexicana, amethyst, witchcraft, belotii, tricuspis, biflora, kewensis, & suberosa all flowered this year for me. They were all started from either a seed or small cutting. I grow them in the winter in my greenhouse, but then move them outside still in pots for the summer. I think that is a wonderful idea, and like Eric said, you could also root a few cuttings from each one around fall to get you started again in the spring. You will have to let me know how this fairs for you, as I think it is a really great idea for us Colder region people who are climate challenged.
