Naturalisation
Well adapted to the
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
Varieties
The currently recognised varieties are:[6]
- G. rigens (L.) Gaertn. var. leucolaena (DC.) Roessler. This variety has grey-white leaves. Its flower heads are yellow, typically without any basal eye-spots. It naturally occurs along the southern coast of South Africa, from Mossel Bay in the west, to Port Elizabeth in the east.[7]
- G. rigens (L.) Gaertn. var. rigens This variety is distinguished by its large 4- to 8-cm flower heads with yellow or orange rays, each with a basal eye-spot. It is only found in cultivation.[8]
- G. rigens (L.) Gaertn. var. uniflora (L.f.) Roessler This variety has leaves that are smooth and green on their upper surface. Its flower heads are yellow, typically without any basal eye-spots. It naturally occurs along the east coast of South Africa, from Knysna in the west, to southern Mozambique in the east. Where its range overlaps with that of G. rigens var. leucolaena, the two varieties often grow alongside each other.[9]
