Hi Maroun
Maples are not as rare as that here, I do have one and there are quite a few in the areas used as landscape. A friend of mine has 2 in Hazmieh so yours should be just fine
They will get the required dormancy in the winter nothing to worry about (again both in Ain Saadeh and in Hazmieh) what is hard to manage is the heat of the summer (think July August). I keep mine shaded in these times and leaves are not a pretty sight even with that lol
Also I know a couple of Nurseries selling Maples very close to us, at least they had some a few months back in the spring, finding them is not the hard part price usually is.
Cheers
