Maypops grow wild here but I'd like to put some passifloras on the lattice around the courtyard. It gets full sun. With our humidity and heat, catalogs that say full sun is not necessarily true unless you want them to burn up and die.
Who is a good source to buy them and will give me good info on where to grow?
I've ordered from Grassy Knolls, Georgia Vines, and Zone 9 Tropicals, and been very happy with all of these. You can call or email them for specific info once you've figured out which plants you want to try. I've found that an east or north facing location is better than a south or west location (less blistering heat during the summer). I plant mine in pots, so they can be moved inside during the winter. If you did that, you could maybe use your lattice to shade the vines from the extreme summer heat. Also, young cuttings don't do too well in the cold of early spring, so you may have to request specific shipping times.
The back of the house faces south with the courtyard or whatever you want to call it. It's a large area as we extended it 80 ft or so. The old area is pretty well planted. It's the new area that I need to do. It has lattice on the east, west, and south. It's open with no shade except some in late afternoon.
I'min zone 8 but will contact those places. With Georgia vines not too far away that is a good option.
