If I read Charleen's post correctly, picture a wooden step-ladder. Drill a hole in the rung, OR in the board you've spread between the front & back sides, and put a bucket in said hole. Could be one of those big 5gal buckets, or something smaller. Make sure the bucket has drain holes, and plant it with a cascading plant. You could do the same thing by drilling a hole in the top step and having the plant cascade over the entire ladder.

I think I am starting to picture it.

Awesome Vertical Garden!
Found you a link and picture.
Went to Lowes Saturday. I went into gardening dept. got me a bottle of fish Emulsion. Then I went into store to where the ladder was sitting. I have a new Smart phone (wish I was that smart) Anyhow I set the fish emulsion on a Toolbox they had on display. I was taking a picture, which I haven't learned how to put on here, BUT, an old man was nosing around the toolbox and knocked my Fish Emulsion onto the floor. Oh, My Gosh!!!! It smelled so bad. One of the folks working there told me not to worry about it. But i was so embarrassed. The man said "I just open one drawer," yep he did but sure made a mess!!
folks don't call me Bumble for nothing. .

Charleen, you weren't the Bumble, the man was.
You are so good to us. Went to all that trouble, just for us.
What a great idea the ladder is. I love the color they painted it.

I can't do something simple it seems but was hoping you would like the story.
some people are so funny and girl...That fish emulsion was smelling up the store. It was sort of funny. Right outside the Restrooms...
whew it stunk !!!!

When Hubby and I went by that area to go to check out. There was a lady cleaning it up. to make it even funnier, she had one of those masks on while she was mopping. Poor thing.
I felt so bad....

Life happens.
