As stated, use native plants only
Please be aware of local native plant populations when using this concept. In much of the US some species of willow and buckthorn are invasive, can out-compete native plants, and can result in a drastic reduction in local biodiversity. I recommend Doug Tallamy's books Bringing Nature Home and The Nature of Oaks for anyone interested in native plant info. The writing is targeted at the US, but they're easy reads and have a lot of good info.
I did/ do something similar on my balcony.
In the early spring this year, I cut some willow twigs and made them root, and then put them into my soil pots.
I use them as living climbing support. I constantly cut off the side twigs that sprout, to enable a linear growth, and wove them into each other.
I'll post some pictures if I can find them :)
Farm all the things!
