Which perennial plants could be grown in a container of only 2.5 inches depth?
I have a ceramic bowl that is quite large but only about 2 and a half inches deep, it has drainage holes in the bottom.
Can anyone think of any perennial plants that would grow well in it? It would have to be something that has quite shallow roots. I'm trying to get a herb garden going, any herbs that would grow well in it? Failing that anything really, I'd just like to use it for something.
Thank in advance!
