Oh my god thanks saltcedar you have no idea how long I have been trying to find the name of this plant thank you very much

You could probably cut the stem into two-foot sections and bury those 6" down in the sand - in shade. They'll likely root and grow. Cut off most of the leaves except newest ones. You can also start these in pots of potting soil in the shade, let them grow a while, then transplant after they form a good root system. I have started them in my basement over winter this way. But they are likely very inexpensive at your local Home Depot/Lowes.

Philodendron selloum aka Philodendron bipinnatifidum.

and it is not very happy .. they can be propagated rather easily ... i would google that .. or the houseplant forum.. get a few to root.. [if you use that latin name in the GW search.. now that you have it.. you might find a couple hundred posts on this plant ...] and throw this thing out ... its potting media is probably failing.. its near impossible to repot a plant that big.. as they tend to tip over... and its ugly as hell .. lol.. sorry ... but some new babes.. with be EXACTLY.. this plant.. and will be in a clean pot.. with new media... and will thrive and bring jouy.. until it looks liek this again.. in ten year ... in the alternative.. simply cut off every yellow leaf about an inch from the trunk .. and see if you like what is left... they are old.. and will not regreen ... and the little stub will eventually fall off ... ken ps: one other alternative.. would be to cut the trunks at 3 .. 6 . and 9 inches ... repot it in some fresh media .... and it will probably regenerate into a nice.. smaller.. beautiful plant.. you can barely kill these things ....
