Since I have no phone line for now, I have to borrow a computer when I can, so I can't stay on long enough to look these up myself.
Can someone find the cold tolerances for the following?
Passiflora Tulae
Passiflora Violacea
Passiflora Serrato Digitata
Passiflora Vitafolia
Passiflora Helleri
Passiflora Lady Margaret
Thanks for any help you can give.
Kay
Also, any tips on getting these to bloom would be great!
Looking for lowest cold tolerances for passifloras
Kay, according to Knoll Exotic plants:
Tulae---minium temps around 40 degrees.F
Serrato Digitata--minium temps. 50 degrees.F
Vitafolia--minium temps 45 degrees F.
Lady Margaret-- minium temps 45 degrees F.
Sorry, I couldn't find any info for the next two.
Violacea
Helleri

Kay, I found Violacea in Dave's plant fliles and it was listed as USDA Zone 9a: to -6.6° C (20° F)

This site says Helleri -55degrees or warmer for blooms. http://www.alohatropicals.com/PV-22.htm
I know Lady Margaret took 26 degrees and didn't lose its leaves last Christmas, P. vitifolia died to the ground, but came back. The temps only dropped that low for a couple of hours and it warmed right back up. LM lost all her flower buds at those temps.
Here is what Vanderplank's book says the minimums are:
P. tulae must be kept warm, minimum 55*F
P. violacea hardy to 32*F
P. vitifolia no minimum given
P. serrato digitata minimum is 60*F and they will still get stressed at that low temp.
P. helleri minimum 50*F
P. Lady Margaret 38*F
Yay! We got our phone back today!
Ada and Susie, thank you both so much for all your trouble. 'Looks like I'd better start figuring out how to get some of them in the house for the winter. I don't even keep my greenhouse any higher than 40-45!. And it looks like it's gonna be costly to keep anything warm this winter.
Oooh, I've got so much reading to catch up on. We were down for 45 days. What all did I miss?

Kay, glad to hear you've gotten your phone back. Hope everything else is coming together for you.
Hi,
I was reading this post, and had a question about my Scarlet Passion Flower, or Passiflora coccinea. I live in zone 10b and thought this would be fine all winter, but it's starting to wither and lose leaves. We've had a couple nights already that dipped slightly below 50 degrees. Could it just be hybernating? Should I cut back all the dead stuff or is it good to cut it all the way back to the woody stem? I'm really new to gardening so this is my first winter. Sorry if this is a silly question, but I really don't know what to do. If it's dead, maybe I should jsut pull it out and start again with something hardier (but it was so pretty and I don't want to!)
Thanks so much, Christina :)
Hi Christina,
I wish I could help you, but this was my first year for coccinia, and mine's not doing much either. Why don't you post you question on the vines forum as a new thread! Maybe somebody can help us both.
Some people have advised me not to fertilize them, and others have advised me to fertilize. I'm really confused about this particular plant, although I generally do pretty well with most kinds of plants.
I think these go dormant in the winter time here, but as warm as your climate is, I would think they would not. Some plants go dormant where ever they are, while others only go dormant where it gets cold.
'Wish I could help. Good luck to both of us.
Kay
Hi,
Thanks for responding. I may just have to experiment, since no one else has given advice. I did post it to the forum under a separate post, thanks for the suggestion. Hopefully someone will come along that might be able to give direction. For now, I plan to cut all the dead stuff back and plant another plant near the 'stump' to fill in in case it doesn't come back. If it does come back then I'll have two pretty plants intertwined! :)
C-
I lost coccinea last year in the freak snow. It definitely can't take 26F
did it come back in the spring?
No, it didn't come back. I lost several passifloras last winter. Hope this winter is "normal."
