Take a look at The Bountiful Container
, by Rose Marie Nichols McGee and Maggie Stuckey. It focuses on veggies, herbs, and fruits that will thrive in containers and gives specific instructions on the size of containers for the individual plants.
McGee & Stuckey also suggest some groupings of plants in the same container for succession gardening, as well as some for looks and/or cooking convenience.
I first saw it at my local library and then purchased my own copy later, after I decided it was a very useful book.
Best wishes for successful container gardening this year!
