I know there was a posted from Indiana who had some red passionflowers overwinter (dying back in winter but still growing back from the roots/base of the plants in the spring). Anyone remembers who that was or the specific variety name?
Maypop is known for being hardy, but mine isn't showing signs of life yet.
I did however succeed in overwintering passiflora caerulea (bluecrown passion flower) in ground here in zone 6 this winter with heavy mulching.
Most sources list bluecrown passionflower as Zone 7. Not sure those would be able to overwinter in 5b, even with heavy mulching and a milder than usual winter. Southern Magnolia is Zone 6+ (with Zone 7+ being ideal) and there is one in town that's been alive for several years.

You may be zone-pushing. If this can barely grow in Indiana, the chances can't be better here.

I don't think it was barely growing in Indiana, but I don't remember the details, that's why I was trying to see who was posting about it because I forgot who it was. I would still be interested in growing that red species though, even if it can't survive in ground here, if it's hardy enough to survive in-ground in Indiana, it's probably hardy enough to survive in a pot in a garage here which means it's less maintenance than the ones that need to be brought fully indoors.
