#Western Australia

• Winged wattle — A rare and deeply fascinating dwarf shrub species, endemic to the temperate regions of southwestern Western Australia, morphologically remarkable for its deep green, flattened stems transformed into broad, wing-like structures (phyllodes) that take over the function of evolutionarily reduced leaves. Popularly known as the 'winged wattle', this species is distinguished by its brilliant cream-yellow or yellowish-white globular inflorescences, displaying a unique and spectacular structural adaptation to dry summers and periodic bushfires.
• Drummond's wattle — A dwarf species of ornamental shrub, endemic to the southwestern regions of Western Australia, renowned for its outstanding structural elegance. Unlike many acacia species that develop phyllodes, Acacia drummondii retains its true leaves, featuring a fine, delicate, evergreen, bipinnate foliage of a deep green hue. The plant is distinguished during its flowering season by its atypical, cylindrical, and pendulous inflorescences (resembling catkins or tassels) of an intense canary-yellow, making it considered one of the most refined and decorative small species within the genus.
• Prickly moses — A species of small thorny shrub endemic to southwestern Western Australia, remarkable for its ecological value and delicate beauty. The plant features true, finely divided, deep green bipinnate leaves, protected by sharp stipular spines located at the stem nodes. Popularly known as the 'prickly moses', this species is famous not only for its brilliant golden-yellow globular inflorescences, but also for its unique capacity to fix nitrogen in the soil and to display a natural resistance against the destructive attacks of the dieback fungus Phytophthora cinnamomi.
• Agonis — A genus of flowering evergreen shrubs and trees in the family Myrtaceae, strictly endemic to the coastal areas of southwestern Western Australia; characterized by aromatic leaves rich in essential oils, small five-petaled white flowers arranged in axillary heads, and woody capsules.
• Agonis marginata — A secondary scientific name or historical synonym utilized in botanical taxonomy for a shrub species in the family Myrtaceae (genus Agonis), native to Western Australia; characterized by evergreen leaves and dense capitate inflorescences. In modern nomenclature, this taxon has been revised or reassigned.
• Red and green kangaroo paw — An iconic species of the Anigozanthos genus, famous as the floral emblem of Western Australia, remarkable for the spectacular chromatic contrast of its inflorescences. The structural plant develops simple or poorly branched flowering stalks, covered with fiery red hairs at the upper part, from which intense emerald-green tubular flowers emerge, requiring strict drainage conditions and a warm climate to survive.
