Flower-stalk height and color of kangaroo paws, flowers varies between the species. Many new forms have also arisen as the result of deliberate hybridisation. The shape of the flowers and the position of the pollen-bearing anthers is a feature which allows pollen to be deposited on the head of feeding birds. Different species usually deposit pollen on different areas of the birds' head. This means that pollen from one species is unlikely to be deposited in the flowers of another species. Anigozanthos species are commonly propagated from seed. In general Kangaroo Paw grow best in well-drained soils in a sunny position. Well-composted organic matter will improve growth. Most species are dormant over winter (some die back completely) and it is important not to over-water at this time.
