Not that I know a great deal about plants (yet) but you may want to include what your climate is and location (shade of a building part of the day or direct sunlight) as this will effect peoples recommendations. for our area (hot sun, sandy soil), we are going for Crepe Myrtles and screens of jasmine and passion fruit vines for narrow spaces.

Do you have a budget in mind? preparation is the key to success, I would consider maintenance how much time do you have to spend on the garden, hedgers are great but to look great require a fair amount of consistant care. Firstly I would do a ph test on the soil, that will determine what you will be able to grow easily, you then need to consider light, how much sunlight does the area get, it looks to be quite compact being a driveway, drainage is another issue as from the picture it looks the have quite a slope to the area, the laws of gravity will have an effect on water infiltration, so plants at the highest point will have less water and the plants at the bottom will be subject to being water logged. I would be mindful of plants with thorns being such a small area and getting in and out of your car scratches are inevitable and dangerous for little kiddies eyes etc. Australian natives are great but most wont tolerate water logging and most prefer alkaline soils and wont do well in heavy shade. My choice would be to find a climber to suit the area there are many to choose from I love Hardenbergia Happy wanderer, Jasmine, honeysuckle and stephanotis just to name a few. Camelias are also something to consider but again all comes down to your soil ph.

Ah! Julie! You were the inspiration for me planting the viburnum. You suggested viburnum to me and provided some photos of your beautiful garden and the viburnum hedges you have. I can only hope mine turns out half as good as yours! You suggested I plant the glossy leafed one, but the horticulturalist I consulted advised against that as they are planted against a brick wall that faces west and gets very, very hot - he said the glossy leaves would burn with the reflected heat. So I’ve gone for the lighter coloured leaves and am happy so far. Thanks for the tips about pruning. I’ll start cautiously!

Hi Polly, I live in SE Qld, so completely different climate from you. Where I live, Lomandra are incredibly hardy and will grow in shade or sun. Westringia are also hardy, They will take part-shade and adapt very well to being clipped to size. I'm also happy with my dianella. They are really great for getting green 'lushness' in shade. I grow quite a few grevilleas. The hybrid ones flower all year round and give great colour to the garden - and the birds love them. I also grow leptospermum, melaleucas and callistemons in areas where my drainage isn't good enough for grevilleas. I also like Chrysocephalum apiculatum as a ground cover. According to the experts it grows in Melbourne. Where I live it's very long-flowering and spills onto paths nicely. I'm growing a few lilliepillies in shady areas, but we had lots in our last garden so I wanted a change. We have no lawn at all in our garden. No kids or dogs so don't need it. There are so many wonderful natives. Our local Bunnings actually stocks quite a few, or you can find a specialist native nursery that will have an even bigger selection. They can give you advice on what will grow well in your situation.
