Australian Plants Society NORTH SHORE GROUP Ku-ring-gai Wildflower Garden Bush foods and fibres • Plant-based bush foods, medicines and poisons can come from nectar, flowers, fruit, leaves, bark, stems, sap and roots. • Plants provide fibres and materials for making many items including clothes, cords, musical instruments, shelters, tools, toys and weapons. • A fruit is the seed-bearing structure of a plant. • Do not eat fruits that you do not know to be safe to eat. Allergic reactions or other adverse reactions could occur. • We acknowledge the Traditional Custodians of this land and pay our respects to the Elders both past, present and future for they hold the memories, traditions, culture and hope of their people.
