The Western plains of New South Wales are grasslands. Their vast expanse flows for many hundreds of miles beyond the Lachlan and Murrumbidgee rivers until the desert takes over and sweeps inland to the dead heart of the continent. In a good season, if the eyes are turned to the earth on those plains, they see a tapestry of delicate life—not the luxuriant design of a book of hours by any means, but a tapestry nonetheless, designed by a spare modern artist. What grows there hugs the earth firmly with its extended system of roots above which the plant life is delicate but determined. After rain there is an explosion of growth. Nut-flavored green grass puts up the thinnest of green spears. Wild grains appear, grains which develop bleached gold ears as they ripen. Purple desert peas weave through the green and gold, and bright yellow bachelor's buttons cover acres at a time, like fields planted with mustard. Closest to the earth is trefoil clover, whose tiny, vivid green leaves and bright flowers creep along the ground in spring, to be replaced by a harvest of seed-filled burrs in autumn—burrs which store within them the energy of the sun as concentrated protein. At the edges of pans of clay, where the topsoil has eroded, live waxy succulents bearing bright pink and purple blooms, spreading like splashes of paint dropped in widening circles on the earth.
Above the plants that creep across the ground are the bushes, which grow wherever an indentation in the earth, scarcely visible to the eye, allows for the concentration of more moisture from the dew and the reluctant rain. There is the ever-present round mound of prickly weed, which begms its life a strong acid green with hints of yellow, and then is burnt by the sun or the frost to a pale whitish yellow. As it ages, its root system weakens so that on windy days the wind will pick it out of the earth and roll it slowly and majestically about like whirling suns in a Van Gogh painting. Where the soil contains limestone, stronger bushes grow, sometimes two to three feet high, with the delicate narrowleaved foliage of arid climates, bluish green and dusty grey in color, perfectly adapted to resist the drying sun. Where the soil is less porous and water will lie for a while after rain, comes the annual saltbush, a miraculous silvery-grey plant which stores its own water in small balloonlike round leaves and thrives long after the rains have vanished. Its sterner perennial cousin, which resembles sagebrush, rises on woody branches and rides out the strongest wind.
Very occasionally, where a submerged watercourse rises a little nearer the surface of the earth, a group of eucalyptus trees will cluster. Worn and gnarled by wind and lack of moisture, they rise up on the horizon so dramatically they appear like an assemblage of local deities. Because heat and mirages make them float in the air, they seem from the distance like surfers endlessly riding the plains above a silvery wave. The ocean they ride is blue-grey, silver, green, yellow, scarlet, and bleached gold, highlighting the red clay tones of the earth to provide a rich palette illuminated by brilliant sunshine, or on grey days a subdued blending of tones like those observed on a calm sea.
