Snow can fall in the highlands at any time between October and May. It was snowing heavily in the Cairngorms last week. Obviously, at lower levels there's less, but that doesn't mean it doesn't fall. Soil conditions will vary from area to area, as they do anywhere else too.
Working with the conditions you have is important. Frilly, fussy plants are out unless you create a micro climate, but the biggest issue in a large part of Scotland is the shorter season - it takes longer for spring to arrive, so soil is wet and cold for a long time, and winter comes in October . Temperatures stay low for a long time, and night time temps in particular mean that some plants will do less well simply because they don't get prolonged warmth, even in summer.
It's pretty much trial and error in the north, but that doesn't mean you can't create a nice garden.
