Trace - I have thought that snake plants and pothos were lower light plants. I haven't tried growing them in direct sunlight, but both of mine are doing pretty well in indirect light(east or west window) locations.

I can tell you that my tri-color wandering jew is doing very well in a south facing window. I also have a spider plant that seems to be tolerating it so far, but I'm keeping a closer eye on that one - we'll see how long into the summer I can keep it there.

Dumb cane (Dieffenbachia) will sunburn in full sun, and sometimes even in partial sun (I had one burn in a west window this winter). All the others in the list either prefer, or will adjust to, full sun, though some of them might prefer lower light, or might take a long time to adjust.

Not on your list, but also full-sun plants:

most but not all cacti (duh) (spines)

Synadenium grantii (you'll have to google for a picture and description, but they're very gratifying plants if you can keep up with them -- quick growers) (toxic)

Codiaeum variegatum (croton) (toxic, bug-prone)

Cordyline terminalis (ti plant) (bug-prone)

Pandanus veitchii (screw pine) (spines)

Aloe spp. (spines, toxic)

Murraya paniculata (mock orange)

Agave spp. (spines)

Yucca elephantipes (a personal favorite) (spines)

Strelitzia spp. (bird of paradise) (leaves will burn if you just set it outside in full sun, but it will adapt and possibly bloom if you gradually increase sun. They're happy with indoor sun too, though less likely to bloom)

many, but not all, palms (bug-prone)

Euphorbia tirucalli (pencil cactus, red-tip) (toxic)

Euphorbia trigona or E. lactea (can burn in excessive sun) (toxic, spines)

Pachyphytum geayi or P. lamerei (Madagascar palm) (spines)

Kalanchoe tomentosa (panda plant) (toxic?)

Araucaria bidwilli (monkey-puzzle tree) (spines)

Kalanchoe daigremontiana (mother of thousands) (toxic)

Tradescantia pallida (purple heart -- another personal favorite)

Pedilanthus tithymaloides (devil's backbone -- yet one more personal favorite, though they may be hard to find) (toxic)

Coffea arabica (coffee plant -- difficult, needs high humidity)

Adromischus, Lithops, Echeveria, Aeonium, Gasteria, Haworthia spp. (succulents)

Ledebouria socialis (silver squill, violet squill) (toxic?)

Gynura aurantica (purple passion plant)

and many more . . .

Out of all the plants on your list, the only ones I would give direct sun to are the jade, the Schefflera (about 4 hours or so) and "Some" to the wondering jew.

Hi Trace..the only plants I wouldn't place directly in front of a southern windows are the Pothos and Sans.
How much direct sun are we talking? Is there a building, tree, something obstrucing these windows, or open?
You can set the Sans and Pothos off the side of your new windows..this way they'll be getting indirect sun.
Oh, what about curtains or blinds? Adding either will block strong sun rays.
As far as the dumbcane, see how it does. Seems to me some can take more light than others..If it starts to burn you can relocate..Unless your north windows are really bright, I don't think a north exporsure would be sufficient for the dumbcane..Especially in winter..
Mr Subjective gave good advice on high light plants. Toni

The Scheff isn't going to like the direct sun. Even in your frigid zone the sun in afternoon gets too hot.
I would only give the scheff direct sun before 10am, otherwise it likes bright but indirect light. The leaves will get white spots when burned. If not enough light on just about any plant it will look stretched with the leaves or branch getting further and further apart.

Hi Tracy. From your list, I have a Dumb Cane (I have many Dieffenbachias), Pothos, Jade, Ponytail Palm and two Rubber plants in front of the same window that enjoys sun from the morning till about 1:00 p.m. My window is not entirely south. It's mostly south but slightly east.

Anyhow, the Jade, Ponytail Palm and the Rubber plants sit smack right in front of this window (just a few inches away) and bask in the sun (but with a sheer curtain!). They love that spot and are thriving. The Dumb Cane (all my Dieffenbachias) are behind that first row of sun lovers. They do receive some sun but less intensely. They are protected by the sheer curtain and by the leaves of the front row. The Pothos is hanging a couple of feet back from the window, and to the side. It receives some sun but much less intensely.

Perhaps you can introduce your plants slowly into the areas you want them to grow in and see what happens. Your plants will let you know whether they are happy in that sunny area and you can adjust them (move them closer, further, away) accordingly.
