Hi http://www.benaranurseries.com have a ALOE ALOE http://www.benaranurseries.com/showpage.asp?ButtonID=158 quick reference chart. This might help.

Emily A permanently roofed al fresco will reduce some summer heat gain (although sitting out there may be uncomfortable) and will do the same for winter. From scanning the comments it appears that you are at a point where you can still may major changes; I cannot recommend strongly enough getting the orientation of your new home right, it will be warmer in winter, cooler in summer and be significantly cheaper (if not free) to run with some appropriately detailed insulation. I do understand the appeal of a floorplan that seems to be all you have aspired too but have seen many a case where people have later regretted those decisions. If you are unsure about the pros and cons of various floorplans then get a design professional (building designer/architect) to give you guidance on an hourly rates basis. good luck

Your site is far too exposed for Maples. They are small trees that really need to be buffered from winds and too much sun by other plantings. They also need the soil constantly moist which will be nearly impossible on that slope. You really don't want to grow magnolias anywhere near the footings of a house. Have you seen how large a tree they are? Since you are in a temperate zone and like autumn foliage I can recommend a gingko tree. It will be right sized for your yard and give you that similar lighter than air look and autumn colour as maples but it's more hardy. Another option are silver birches. I would hedge the boundary for privacy and also to cut down winds to your garden which will dry out the grass and scorch it. With that slope you are going to need more rocks I think to prevent your topsoil from washing away in the first rain. It's really no use of us to provide you a list of random plants. What you need to do is put together a series of photo's of gardens you like the look of, then find plants to match that style. If you don't plan gardens then you end up with the ubiquitous suburban patch of grass and odd bushes look instead of a lovely garden.

My house has a bay outlook in eastern Tasmania. This is the street side. Would like some suggestions on planting in front of the house. On either side of the driveway are clipped formal hedges. The area only gets minimal sun in the morning. Would prefer to keep the height under the window, all the same plant and a coastal vibe. Thank you!
