Hedge in 15cm depth space..?

Londonvictoriansemi

Hello I've just bought a new house (victorian semi in London) that has a paved front garden for parking. To the right is a small bed (15cm depth - no that is not a typo! and it is 5 meter in length). It is currently just filled with gravel.


In my dreams I would love an evergreen hedge in this space, but I am aware the depth of this bed is only 15 cm...!

Is there anything that would be suitable here? Or should I stick with bedding plants/ something else? 

Thanks and have a good day

When you say 15cm, do you mean the depth front to back, or the actual depth of soil available?

Hello, thanks for replying. The 15cm is the distance front to back of the bed.

There is soil beneath the current gravel which is there (for as a far as id keep digging)

You'd struggle to keep most hedging looking decent with that sort of sizing, unless you have enough room either side for it to grow, and can get it established to start with  

You could grow something low, but again - it depends on what you need a hedge for. If it's to give a bit of privacy on a boundary, that might be difficult.
