Starting a Herb Garden

I'm sure most of you have gone through this - you're at the store buying ingredients for a roast chicken or salad, you need thyme, rosemary, sage and parsley. But you only need a pinch or a dash of particular herbs, leaving you with enough leftovers to make the same dish five times over, yet you know they'll all be spoiled and wilted before you get a chance to make the same meal again.

How nice it would be if you always have some herbs in the garden where you just need to pluck whatever amount that is needed ?

Right now, I do not have a garden space to plant my herbs, so we are planting in these long "pots". In the future I would like to have a real garden with herbs sectioned beautifully like this:

Dream Herb Garden

Right now, I have to be start small, and these are what I have:

Moss-curled parsley, Rosemary, Marjoram (family of Origanum), Celery

Thyme, Coriander, Sorrel, Celery(curly)

Also in individual pots, I have Chillies, Wheat Germ Grass, Thyme, Chillies and Garlic Chives, still waiting for some greens to appear.

Rainbow also wants to be part of my herb garden project.

Which is longer - the pot or Rainbow? :)
