These days I am leaning toward a more natural and loose garden style, definitely influenced by the New Perennialist Movement from the Northern Hemisphere, and my undulating site. The style suits the site we have been on for 2 years, compared to the more conventional formal gardens and hedges at our old house. Add to that the fact I cannot access the vast majority of the garden with any form of water other than that provided by Mother Nature! So tough, beautiful, drought and wind proof are the main prerequisites! Plus STRUCTURE STRUCTURE STRUCTURE!! Doesn't matter if it is hedges or evergreen shrubs, the garden has to look great 12 months of the year - and preferably with seasonal variation.
Here are a few snippets from my nearly 2 year old garden nearest our wee house (hut). Main structure is Muehlenbeckia astonii balls, Astelia, Miscanthus, Calamagrostis, Stachys, Phlomis, and Libertia grandiflora. Then seasonal variation from Scabiosa, Strawflowers, Achillea, Bearded Iris, Artemisia, Dahlia, burgundy Cornflower, Poppies, Sanguisorba, Anemone, Knipofia and of course - Alchemilla mollis (Ladies mantle). We have a 'no mow' lawn of Leptinella and Pratia alba, which is gradually winding its way into the main garden. Not sure if I will leave it or not. This will eventually be an accommodation hut, so not looking for too much maintenance.
