Willow is easy to grow, and it will come away from ends shoved into damp ground. The only thing is that it's inclined to be a thirsty plant, and it'll get it's roots out looking for water. If you're not careful it'll fill drains and soakaways with them.
That said, it can be very beautiful as well as one of the most useful plants.
If planted as a windbreak around a seating area, it will need pruned anyway, and that stuff can be used for basketry.
The bark makes great cordage and the off cuts make really good charcoal drawing sticks.
Boiling up the bark releases lots of tannin and gets used to kind of stabilise/ colour other fibre ropes and cordages, like nettle.
