It's refreshing to see nautical, navy BLUE. Everyone is saying the same thing for the most part - just introduce another color, definitely bright (yellow or orange IMO) and it will make it more current. What I really like is how your style will withstand the test of time - and with minor updates now and then it will always look fresh and "current".

You must be in a tropical zone - I see palm trees .What zone are you in ? How long do you plan to live in this house and are you married to the grass ? How long and wide is the garden ? Can you make a shot from the fence toward the house ( house in center ) ?

Sorry I am so late coming to your site - you are an inspiration to all, homeowners and advisers alike. For your planting advice, I suggest you call Merrifield Garden Center to see if they will come out your way. They currently have wonderful garden centers in Merrifield and Fairfax (both in Fairfax County) and a new one in Gainesville, but they may come further south to wherever you reside. (www.MerrifieldGardenCenter.com) Even if they don't send designers to your area, they are worth a trip to see their huge selection for a day of pleasure and inspiration, or to pick up some plants. Most of my clients are in the Fairfax and greater Washington area, but I am currently living out west below Front Royal, VA on the Shenandoah mountainside - wonderful views. cascio.offsite@gmail.com

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!
