CONTAINER GARDENING TIP OF THE DAY
Sometimes we are reluctant to grow veggies because of the yields (unless you have space for several pots).
But, and for instance, garlic, leeks and shallots/spring onions make great container gardening edibles, and as you guess, join many herbs by not taking up too much space and by making for good repetitive harvesting. These three also have very few insect and disease problems, which is a bonus, and they have shallow roots too, so your container choices are more varied (can be wide and shallow).
With style in mind too, your containers should be sized to the area you have available and plants should be sized to the container.
