Gazania rigens (syn. G. splendens), sometimes called treasure flower, is a

native to coastal areas of southern Africa. It is naturalised elsewhere and is widely cultivated as an ornamental plant
.

Description

Gazania rigens is a spreading, low-growing,

obverse
of the leaves is shiny green, the grayish white lapel.

Like all compounds, gazania flowers in flower heads that are often taken for simple flowers. The capitula are solitary at the end of

ligulate peripheral flowers, whose color is very variable. The orange-yellow flowers are however the most numerous, often with black spots at the base of the ligules. The fruit is an achene
, containing several seeds.

Naturalisation

Well adapted to the

Theodore of Gaza (1398-1478), who translated the botanical works of Theophrastus, from Greek to Latin.[citation needed] It is a weed in the islands of Madeira, Sicily and Sardinia[citation needed
].

In Australia, where it is known as coastal gazania, the species has become naturalised on coastal dunes and roadsides in the Central Coast and Sydney regions of New South Wales as well as the coast of South East Queensland. In South Australia it is found in the southern Mount Lofty area as well as on the Eyre peninsula.[1][2]

Cultivation

Gazania rigens is grown for the brilliant yellow of its blooms which appear against blue-grey foliage in the late spring and throughout the summer. Plants prefer a sunny position and are tolerant of dryness and poor soils. Quite indifferent to the nature of the soil, it looks especially for the sun, its flower heads closing when it is in the shade or when the weather is overcast. It adapts well to drought, heat and strong sun, unlike many other flowers.[3][4]

Flowering from March to October in the

temperate regions this plant is usually grown as a half-hardy annual, though it can tolerate light frosts.[3]
