How can I cover an unsightly crawlspace window well right in the middle of my landscaping in the back of my house?

What is a 'crawlspace window'?

Is it possible to put a pot on it? Or grow something that sprawls to cover it?

I don't know what a 'crawlspace window' is, either!

???

Curiosity aroused!
Is it a window or is it a well?

Sorry, everyone. What I mean is a crawl-space well.

I might clarify - I am in the U.S. Under our homes is what is called a "crawl-space".It is about a 3 foot tall area and is for ventilation and also provides access to our plumbing pipes. Most houses have access from the outside - hence a well like area with a window. I hope this explains it better. Houses that have basements do not have crawl spaces.

Ah... not something that we have in the UK so far as I know. Try trellising with some nice climbers

Can you post a photograph?

I put a frame of wooden 1/2 sleepers around mine covered the drain cover in weed repellent material so that I could easily lift the coloured shingle I filled it in with if I need to. and then put a conatiner of bedding slightly to one side

Thank you for your replies! More suggestions are welcome, too!!
