The fence will end up being a modern picket fence, We aren't sure if we should grass the two squares or plant it out, it's a nice sunny spot, but we have nosey neighbours that we are trying to make disappear, if then it becomes more private then a seated area could be really nice, Hopefully the right plants will work or we will have to go with plan B, of installing barbed wire and two wild Dobermans!

And I would be planting trees – real trees not dwarf versions of trees and no more palms (unless you want to have palm tree themed garden – in which case a lot more palms are needed). I am not advocating planting forest giants but there are trees that will provide shade, shelter and a sense of scale that you won't get from yuccas and buxus and mondo grass and succulents alone. But before you start buying those trees you have a few decisions to make and a bit of analysis to do. 1. Orientation – you need to understand the basics of winter sun and summer sun, how much westerly sun you welcome and how much you need to shelter from it; where your prevailing winds blow from and whether this changes with the season also. So, once you've worked out where you want the sun to penetrate and at what time of the year, how to allow for wind, frost, whatever... you need to 2. Decide if you want a predominantly native garden, a range of deciduous trees or a completely eclectic selection (like the best 'English' gardens – which are planted out with plants from all over the world – Indian subcontinent, Asia, Africa, The Americas etc. Even some from Australia!). 3. Now the tricky bit – what do you love, i.e. which trees and plants make your heart really sing – and hopefully for more than two or three weeks of the year? Once you have that list which of those are likely to be happy in your climate, in your soil and with the amount of gardening attention (watering, feeding, pruning etc) that you're likely to enjoy lavishing on them. Your long list will by now be a much shorter (and more manageable list) but trees are what make a house look bedded in and part of a landscape rather than just sitting out in the open in a way that is both self-conscious and a bit awkward. Although, again I guess you could embrace the suburban awkwardness and go all Howard Arkley in which case keep it all small and suburban... But it is your garden and your house – make it look like what you want your house and garden to look and feel like! Good luck!

Where is your house? Low maintenance plants depend on the zone. I wouldn't plant in your rock skirt. Ideally you'd put your rock skirt around the house and then planting beds outside of that. The skirt keeps mud and dirt off the house and let's you spray for bugs etc. since your skirt runs right up to the driveway on that side, I think your options for plants would be some large pots or window boxes. I'd paint your foundation the same color as your grout in the brick to help it blend in.

You can get feedback from a local nursery. My garden is 15 years old. I've planted what is pretty and now know what will grow and what won't! I have a peony garden, hydrangeas/ hosta on north side, catmint in dry areas. If you like to garden this is an ongoing process! If you just want to plant and move on, think low maintenance shrubs, dwarf lilac, hydrangea, and boxwood.
