Passiflora help please

[canadianplant]

Well, dispite having heavy snow, and supposed -10 temps a night or 2, my passiflora is alive. Ive buried the bottom half 2 feet deep , mabey a foot wide in leaves, then wrapped in plastic ( not sealed yet). No real leaves on eh bottom, but the tops are all green still. Im not sure if i should give it a try and leave it, or if i should try to cover them in some way. Im not as familiar with these as with other plants.......

Thanks everyone

I'd like to learn more, too, and so hope we get some input.
Last year I tried to overwinter P. caerulea with mulch; it was up by the house. Didn't work.
This year I grew P. coccinea. I dug the roots and lower stems last week after the freeze and brought it inside. Not confident it will survive.
Now, if I was at all smart, I'd just grow my native P. incarnata....

LOL, its sort of hard to find incarnata up here, whih is hardy to zone 5 or 6 before any multch. I dont even know what species mine is ( was jut labeled blue and white sp.), but it has the teltale "pot leaves" of the cerulea. Heres some pics of it...... Usualy all passiflora ( except incarnata) are generaly very frost sensitive. I think paul mentioned getting a cerulea to survive where he is.

As or temps, im not exactly sure what they are in that area. The lowest temp this year recorded at the airpot was -9C, but my thromometer in my yard hasnt recorded anything below =2C in the last few weeks. LIke i said i multched the crap out of the bottom half, and left the top half of the vines exposed 9 ive already tried to grow the passiflora from cuttings, which failed.

i almost bought some coccinea seeds. The red flowers are different from most passiflora and its apperantly hardy to zone 7.... let us know how it goes dude.

Jesse,
that is a much better mulch pile than what I used last year for my P. caerulea. Hopefully your better efforts will pay off.

This year, the new (planted April) P. coccinea saw -3 oC before I dug it. The leaves that were right up against the wall survived.
The foliage grew great and covered a large trellis. However, my complaint was that it did not bloom at all until October (photo below) and had dozens of buds about to open when I got that freeze. If the freeze had held off, like happened last year, it would have been spectacular in November.

Wow dude.... thats very nice.

Personaly, im not too into flowers.... but these really add a crazy tropical vibe to the garden, even incarnata. Ive finally found out a few things about caerulea:

They apperantly can take from -8c to about -23C. This depends on how dry they stay. Ive found many sources stating that P cearulea grows best in crumbled brick

My friend is sending me fresh incarnata seeds. And as a failsafe, im also ordering some. They have the best chance of survivng here. They used to grow up to Ohio i belive, and my climate is close to theirs ( a bit colder normaly, but in my time it is quite similar).

The ground was a bit wet when i buried it. And its a warm corner. Mabey i shuld take the plastic off for now to let it breath. The temps arent too cold yet to do any damage.
