English: Gazania rigens, sometimes called treasure flower, is a species of flowering plant in the family Asteraceae, native to southern Africa. It is naturalized elsewhere and is widely cultivated as an ornamental plant. Gazania rigens is a spreading, low-growing, half-hardy perennial, growing to 50 cm (20 in) tall and wide, with blue-grey foliage and brilliant yellow, daisy-like composite flower heads throughout the summer. It is a herbaceous plant that is perennial in South Africa and in the Mediterranean regions, and annuals in the gardens of colder regions. Low enough, it rarely exceeds 30cm.
