I live near San Francisco, in California , which also has one of the few Med. climates. We have 3-4 months of continuous drought, each year during summer, so water preservation is a concern. Any plant i list here regarding water use, is a mature sized plant. Drought tolerant: I've never watered any of the Mexican Sage, which were on my property when I bought it, because they never need it. Long flowers of a deep lavender hue attract hummingbirds every day. c. 5 feet tall by just as wide. There are many forms of salvia that are drought tolerant. - It took me a long time to take to Succulents, but after I remembered my grandmothers growing ' Hens and Chicks' in her cottage garden, I added a dozen or so to my rose garden. I have several growing in a low bowl shaped container to show off their growth habit. I find their smooth texture adds interest to a rose garden. Pomegranite I keep mine to c. 5' tall by 6 feet wide, by never watering it. Since reading that the climbing rose, 'Sombruiel' is drought tolerant in our area, I plan to move mine so it is in the same bed as the Pom. Mexican Primrose, pink flowers that bloom nearly constantly through summer. plants are about 2 and 1/2 feet tall. can be invasive if given the right conditions. -Allysium, the white form has longer roots and needs less water. -Many of the native Med. plants are drought tolerant, allysium, lavender et cet. Shrub;'Breath of Heaven' has a great scent, and can be grown as a fragrant hedge. Last year I decided that any plant in my garden was going to receive a minimal amount of water during our drought and those that lived could remain. This did, to my great delight. Snow in summer' sorry I forgot the Latin name which begins with C... a low growing plant that spreads over an area of c. a yard. silvery green foliage and small white flowers. Rose Campion, another med. native that has silvery gray leaves. a flower that has been growing in cottage gardens for hundreds of years. I have it growing beside 'Westside Road Cream Tea' I do like herbs planted amongst my roses: smaller forms of rosemary, oregano, there's some fancy forms 'Kent Beauty ' is one of those, mother of thyme makes a deep green carpet and the flowers keep the bees happy. Lemon verbena near a path gives off a lovely and refreshing scent as one walks by and touches it. Poets Jasmine, again on a north facing wall so the shade lessens its' need for water. I'd plant it by a pink remontant rose as the jasmine does not re-bloom. Nasturtium. The hummingbirds love 'Empress of India', a red nasturtium. Forget-me-nots, I plant them on the sides of rosebushes where they only get half a days sun, and need less water that way. Average water: Scabiosa, there's a mauve form and a purple form that are very pretty. Violets and Parma violets give winter interest, Parma violets are water wise plants when grown in partial shade. Pelagoniums, I grew up calling them Geraniums, I have 'Roxanne' and 'Electric Blue'. Lilys. I prefer the scented Oriental lilys to the scentless Asian hybrids. I had to move all my 'Casablanca' lilies to a pot on a pedestal because snails ate an entire bed of my lilies. Water Wise, (Not quite drought tolerant, need to be watered twice a month in summer here) Lavender. I water French Lavender 2-3 times during a summer and Spanish lavender once a month. I find the shorter forms of lavender need watering more often so I don't grow them anymore. I plant any of my largest rosebushes which don't need support furthest out from the faucet, because they get watered only once a month in summer, and rarely in the other seasons because we do get some rain (usually) the rest of the year. Large self-supporting rosebushes: spray 'Cecille Brunner' I've seen this grown so it has one large basal cane and been pruned: -Into a large balloon shaped shrub. -into a hedge. Each plant makes a wonderfully fragrant hedge with good re-bloom, c. 8 feet long, by 3-4 feet tall, depending on how tall the person wanted it. My neighbor grows hers on the side of a shed. Mme. Alfred Carriere, this is drought tolerant when mature, in our climate. I only watered it twice this summer. I keep it to c. 6 feet tall by c. 5 feet wide, by shearing it 2-3 times back, each summer. Monsieur Tillier, can reach 10 feet tall by nearly as wide. In general the larger the canopy of a large rosebush, the deeper the roots grow, and are able to access levels of water that shorter rosebushes cannot. Susan Louise' a marvelous Hybrid Gigantea that blooms from February through December locally. Produces large roses in profusion that are a fresh hue of pink. Can be grown as a self supporting shrub, c. 18' tall by 9' across, which has the sillouette of an apple tree if limbed, I've also seen it grown as a 25 foot long climber on a 4 foot tall fence. A nice but light fragrance. - since your sister loves Lady Hillingdon, perhaps she'd like 'Anna Olivier' a shapely honey hued Tea rose with an intense fragrance, it's more richly hued sport is called 'Lady Roberts' and I envy her having such a sublime rose given her name. -Mrs. B.R.Cant' big pink roses on a big plant. I water this only half as often as I do my smaller rosebushes, such as my Hybrid Teas, and it doesn't seem to mind. Clematis; I plant them on the North side of the house so they get shade, and therefore need less watering. c. jackmanni is easy to grow. Best wishes Luxrosa

Dear totalli, what a shame, so depressing to get all those negative messages. I have grown roses on the "wrong" rootstock and I have to say , yes they don't do so well here in the west. However one solution could be to have a go at growing some cuttings to see if they could grow on their own roots. Some will and some won't- For instance I have a golden wings that is ok , and Seduction grew quite well into a low hedge, all from cuttings,but Peace was useless. Lots of heritage roses are grown from cuttings. Save some pencil thick sticks about 20 cm long from pruning and put them in as cuttings in a sandy and coir peat mix in a pot and keep them watered, you may be surprised.Another idea rather tricky , would be to " bud" small slivers of the rose onto another well grown base plant, but this needs to be done in January.Books could tell you how, or do have a green fingered friend? Good luck.

Dear Jeevers, yes there is a noticable difference in the flowering of trees around Perth, isn't there? I think this is usually put down to genetic variation, coming from seed grown trees. You can see it in the colour range of Eucalyptus ficifolia, the red frowering gum that put on such a show in mid to late summer- some trees are full of flowers and some have washed out colouring. The jacarandas vary too, I've seen some that flower either very late or early and some that hardly flower at all.

There is a small section on Oca in the book, "The Garden Gurus - A Guide To Water Wise Gardening" by Trevor Cochran and Neville Passmore. This book is quite specific to WA gardening and conditions. I'd assume because there is a section on Oca, they can be successfully grown in at least some parts of WA and can be obtained locally. They also have a website www.thegardengurus.tv. I tried emailing this, but I got no reply - frustrating!
