Wow Walt, thats some cold down there.
thanks for sharing this. These are great plants are common throughout florida. They are becomming more popular here in Tally and recover fast from hard freezes.
this year mine defoliated as well but looks good as new now . under canopy and in warmer spots around town they did not show damage.
awesome plant and I keep planting more

Philodendron selloum Grow outside down here @ 42 deg south never had mine burnt by frost . Amazing recovery

Philodendron selloum is growable in Jacksonville, Florida, where temperatures will get below 20F. Surprisingly hardy.
I got rid of the ones in my yard after the 2005 hurricanes. They tend to crawl across the landscape, take up a great deal of space, and harbor colonies of carpenter ants in cavities at the bases of the petioles. In their place are a whole lot of palms, heliconias, hippeastrums, and a few Simpson stopper bushes. A Carpentaria planted before their demise now has about 4 feet of clear trunk, and a stopper bush planted in 2006 is already about 15' with nice bark and elegant small deep-green leaves.

Walt, I have always followed your picture travels around the lake you live near (you may want to provide your photo links) and I am astonished that you have damage to P. Selloum but have coconuts growing not too far away. Amazing microclimates in your area!! It is also equally astonishing that your have the extreme damage to the Philodendrons but relatively small damage to your Ravenalas. BTW, your Ficusl ooks great!

Around me, all or most survived the 80's freezes. The plant is nearly indestructable.

P. bipinnatifidum (aka P. selloum) is amazingly hardy, grows beautifully in landscapes here, we see at least one long freeze (10+ hours) each year, absolute min of 22-24F most years. They are evergreen under canopy in a typical winter, burn or defoliate under open sky depending on the temp (23F seeming to be the threshold for major leaf-damage or defoliation in the open). In my courtyard, even in large containers, they usually defoliate but they regrow new leaves each spring from the top of the stem...neither trunks nor roots in containers seem to have a problem, though any aerial trunk-roots will go to mush after a hard freeze. Though I wouldn't expect a containerized specimen to survive bad winters in the southeast, though. Trunks probably go to the ground once temps dip somewhere into the teens.
Tony Avent at Plant Delights Nursery in Raleigh, NC (zone 8a) has supposedly overwintered these as returning root-hardy perennials to about 0 degrees F with typically long NC freezes. I have seen other anecdotals that they are grown as diebacks in parts of Tennessee as well. Brrrrrr.
I'm trialing some of the spectacular old Evans and Reeves hybrid P. x 'Evansii' this year in the ground, bipinnatifidum/selloum is one of the parents and this hybrid is known to have some good hardiness, but not sure if they can take as much as bipinnatifidum, nor whether they've been tested to much extent north of 9b in the humid south.
A friend planted planted the dwarf 'Xanadu' last year in a suburban setting that probably sees about 20-21F in the open, they're under an overhang so protected, but they did very well, just a little bit of burn. Look great presently.

"As I stated, my selloums can't maintain a vertical trunk, but fall over and grow laterally. They are creeping farther and farther away from their original planting area."
Walt , with some effort you should be able to get them to climb up some palm trunks .
I have made sure I plant most next to a palm or tree , and when they start getting a bit of a trunk , I will start winding strong rope around the Philo and host and try and get them closer .
If you have a strong vertical sucker , you can always cut off the creeping space hog . I am sure someone would take it off your hands .

It's good to know your P. 'Burle-Marx' has recovered, I have a small one and haven't the courage to put it in the ground until either it gets larger or I top it to make a second plant for security. I also have found that Monstera deliciosa is quite root-hardy here, I bury the stems and though they defoliate under canopy below about 25-27F, they pop right back in spring. My large plant is already quite full again, leaves are large and splitting. Other tropical aroids I've found to be good here in my 9a location as perennials and that have some leaf hardiness under canopy are Philodendron mexicanum and good ol' Epipremnum aureum (Pothos), the latter seems unkillable if some stems are buried, even in a good long freeze. But they're too slow here in shade to make enough of a recovery to look impressive by the end of each season. One that didn't even defoliate at 23F under canopy was Syngonium podophyllum, this seems just as hardy as P. bipinnatifidum. It grows fast (as I think all you Floridians know)...I can't wait to see it climb the trees and get its adult foliage. Jury's out on P. subincisum, seemingly root-hardy as I had a smallish one come back this spring, but it's in a chronically dry spot and isn't growing much, it is disappointingly slow for me.

Large, pre 1980's freeze specimens are all around Tampa Bay.
