I have three small Rhapis excelsa (lady palms) that I have been growing up.  Eventually they will live in my south facing living room with three walls of windows and 12' ceilings.   Winter is pretty cloudy here so they won't get blasted by the sun.  

Right now they are not even pushing 12 inches and I'd like to put them outside for the summer to spur on their growth.  I will place them in a spot with no afternoon sun, but any other recommendations as to minimum temperature, etc. would be much appreciated.

Mine grow in a mostly shaded area on the north side of the property, tight up against the house.  They tend not to like the temperature to go below 20F.

That is much colder than I expected.  Sounds like I can probably keep mine out for the vast majority of the year if I want.  We don't typically go below 25F, the last time was 3 years ago.

Rhapis look best when in a good amount of shade. Be careful not to over fertilize, as Rhapis burn easily and require little. I like to water mine with seaweed extract and fish emulsion to give a little color boost. 

I’m sure they would do great outside year round!

When established in the ground they can take an occasional low 20s temperature with overhead canopy. In pots, not nearly that cold because the soil in the above ground pot can freeze, thus killing the Lady palm. I'd bring them back inside before any freezing temperatures occur. 

Thanks for all the info guys.  The ultimate goal is to get these fairly large to add some nice greenery inside during the winter.  I'll probably keep them out April - Halloween going forward.
