We have a back yard rather than a garden, a couple of small beds and some window boxes at the front. I'm thinking about planting some flowers for the summer but - black thumb alert - I read the seed packets and things like sweet peas say "plant six inches apart", how many can I put in a pot? Can I put anything else in as well? It just seems as if with a 12" pot you can't really put more than one!
What is good in pots also? At the moment I have bedding plants (violas and primroses I think) in the window boxes and large perennial herbs in pots (lavender, oregano etc).
