The seeds are removed from the cone and the sarcotesta is removed by soaking in water, the seed is then roasted and eaten. The seeds are also used to make a flour for damper, and the pith of the trunk is used to make a type of bread.


Macrozamia riedlei, also known as the zamia or zamia palm, is a cycad plant native to southwest Australia. It is often found in jarrah forests and can grow up to 3 meters tall, with glossy green leaves and large cones containing edible seeds. The plant has a close relationship with nitrogen-fixing bacteria, which also produce toxic substances that can be harmful to animals. However, when properly prepared, the seeds are a favored food source for birds and humans. M. riedlei is also cultivated for ornamental use in urban and domestic environments. The plant has a long history of use by Indigenous Australians, who have developed methods for safely consuming its seeds. It is also an important food source for various animal species. In cultivation, M. riedlei can reach up to 2 meters in height and is well-suited for containers and rockeries. It is a slow-growing plant that can tolerate low light and temperature, making it a popular indoor
