Australia has the unique status of being a continent in addition to a country. It has a wide range of climates, ranging from near tropical in the warmer north to temperate in the cooler south. Because of its isolation, many Australian species of plants are unique and native to Australia, although many are now grown in other places. Many types of Australian plants have a number of sub-varieties.
Australia is home to many different varieties of Acacia. Acacia are thorny plants that are often large shrubs, but sometimes can grow as medium to large trees in Australia. Some varieties, such as the Acacia mearnsii, are commercially planted for use in the tanning industries. Australian aboriginal peoples have used the seeds and roots of a number of acacia species. Some species of acacia seeds are used in the "bush food" industry as flours in breads and flavorings in ice cream. With over 900 species of acacia being native to Australia, these flowing trees grow throughout the continent with some varieties preferring full sun and others doing better in shade.
Over 1,000 species of daisy are native to Australia. Some native daisies grow as shrubs while others are herbs. Of the herb varieties, some are perennial herbs, with others being annuals or biennials. Daisies grow in a wide range of soils, including clay, sand and loam. Native varieties of daisies will grow in soil ranging from wet to dry. Because of the variety of native daisies, a form of native daisy exists for almost any planting need. Most daisies do best in full sun.
Kangaroo paw include flowers in the families Haemodoroideae and Conostylidoideae. These plants are native to Australia and parts of New Guinea. The clumping plants, found primarily in southwestern Australia, grow to over 3 feet tall and 3 feet in spread. They grow from rhizomes, with the flowers growing up from the center of the plant on stems that are sometimes taller than the plant. These unique flowers have fuzzy outer portions that look very much like a kangaroo paw. They often have a flower growing from the center of the paw-like structure. Kangaroo paws are most often red or yellow in color, with a few species being an orange-red. Kangaroo paw will not tolerate soggy soil and will only grow in soil that drains well. Sandy or sandy loams are ideal soils for this plant. They grow in full sun and require plenty of water.
