Building a garden with a purpose?

So today we got in and dug up the weed patch. Yes it was a veggie patch at some point, and we do still have yellow zucchinis growing in there, AND some pumpkins!.

Now we just need to get some seedlings to plan. I really want to get some of the diggers seedlings, the heirloom variety. I am so not interested in buying the ones that have been modified so that they only can grow once, and you can't save any seeds, what a joke!

Also in Tassie, this time of year you can't grow a hell of a lot. It seems we can plant onions, broccoli, cauliflower, and cabbage. We already have more silverbeet than you can poke a stick at, but I really don't know what to do with it all? We worked so hard I have blister on my hand. (Either I'm overworked, or I'm precious, I tend to think the latter!)

I only have to work 15 hours this week, so I should be able to get out in the garden a fair bit and turn it into something special. See we have never had a garden. And to be honest I'm not really into 'pretty' gardens, they have to have a purpose, I don't see the point in having a heap of pretty roses, when all they do is please your aesthetics, I need a garden that will feed us, will nourish us. There are a few plants I am going to have to grow. Boronia and Jasmine for a start, they just have the nicest scents, and make me feel all happy and hippy when I smell them.

So if anyone has any idea of how to plant a garden (not veggie garden) that serves a purpose, AND looks nice, I'd be greatful to hear about it.
