There are 11 species of kangaroo paw (Anigozanthos spp.) endemic to Western Australia. Kangaroo paws are herbaceous perennial plants with tubular flowers that look like claws. Some species bear flowers covered in tiny hairs. The brightly colored kangaroo paw flowers bloom August to October. A. flavidus is the most common species grown in the U.S. and one of the easiest kangaroo paw seeds to germinate. Kangaroo paw is hardy to USDA zones 9a to 11.
Add cactus mix to the seed-starting tray, to within 1/4 inch of the rim, and water until the water drains from the bottom of the pot. Water it again, stirring the mix to ensure that it is uniformly moist and allow it to drain completely.
Place the tiny kangaroo paw seeds, 1/2 inch apart, on the surface of the soil and cover with a 1/4-inch layer of sand. An easy way to plant tiny seeds is by moistening the tip of a toothpick and lightly touching the seed with it. The seed should stick to the toothpick, allowing you to place it in the desired spot on the surface of the soil. After planting, use the plant misting bottle to moisten the top layer of sand.
Place the tray in a bright area, but out of direct sun. Keep the soil moist, not soggy, until the seeds germinate, which should occur within 40 days.
Transplant the kangaroo paw seedlings into individual pots full of potting soil when they reach 2 inches in height. Pour fungicide over the soil in each pot, according to the rate suggested on the package.
