Can you attach a photo? Where do you live? Climate.

Be aware that artificial turf can get very hot underfoot. You could lay a narrow old brick or limestone paver path to clothes line for easy access and plant ground covers or low profile herbs (eg.oregano and thyme) to use in cooking. Hardy herbs or flowers such as rosemary, lavender, geraniums against the edges of the space toward the back. Even add some large long troughs of flowers on the retaining wall to pretty up the area. It looks like it could get quite warm there but maybe a jasmine or similar climber to climb up a frame attached to the part of the large wall where there is no clothes line. Good luck, it will be a lovely space I'm sure once you get started.

Flufftop, there have been many good suggestions in this discussion. You already have two 'WOW' factors in your front yard...your lovely cottage and the tree. Whatever you do needs to link these two with the remainder of the garden and that's not an easy thing to do when you have a variety of ideas coming at you from all directions. Walk around your neighbourhood, go to Diggers for inspiration but also go to your local nursery and ask if they have a garden advisory service. Another option is to find a local garden designer (www.aildm.com.au) and have them visit your garden. They have the knowledge to tie all your ideas and thoughts together. They will suggest ways to incorporate all, or some, of your wishes into a unified design which can be implemented immediately or over a period of time to suit your budget. It will cost you a fee for an hour or two ,or more if you get a plan drawn up, but will save you money and disappointment because you'll be eliminating guess work and mistakes. Best wishes Arthur

Something like silver birch trees don't take up too much room but will provide some height and interest. Personally I pick out natives, after asking local garden centres for those which are natural to my area. I've used black mondo grass across the front of my walls with purple fountain grass behind it. The fountain grass really takes the summer heat, doesn't need much water and self-seeds. It's grown slightly taller than me after a few years. I have, what I call a 'survival of the fittest' garden. Over the years, I've experimented with all sorts of plants. Eventually, only those that survive with little help, and almost no extraneous watering, get to stay. One of the key things I did when planting out my garden was to dig down into the soil and lay a mat of used, natural-blend carpet underlay (not the more synthetic types used these days). Just ask someone getting rid of their old carpet- it's easy to come across. Above the carpet underlay I added water crystals, then put the soil back on top. After the gardens have been established, I haven't need to get the hose out since. I do have lots of succulents around the place, some native plants and ornamental grasses. I hope this helps.
