Gazania splendidissima is an eye-catching perennial with striking greyish semi-succulent leaves and golden-yellow to orange flowers.
Gazania splendidissima is a perennial subshrub to 200 mm tall with woody prostrate branches. Leaves clustered at branch tips, simple to pinnatilobed, semi-succulent, greyish on upper surface, white felted-araneose (cobwebby) beneath. Flower heads 40–65 mm in diam., radiate, solitary, involucre with 2 or 3 rows of bracts inserted on the rim, connate area densely mealy with numerous bristle-like hairs, maculate due to black colour of the hair base and surrounding involucre. Ray florets neuter, 12 to 21; lamina 15–30 mm long, golden-yellow to orange, basally marked with black adaxially. Disc florets bisexual, numerous, yellow. Fruits narrowly obovate, hairy, crowned with a biseriate (in two rows) pappus of scales.

Flowering time: August–October.
The species is currently listed as Vulnerable (Magee et al. 2011). The coastal habitat to which Gazania splendidissima is endemic is threatened by coastal diamond mining and disturbance caused by vehicles. However, the populations appear to recruit readily from seeds so that young plants and seedlings are regularly encountered (L. Mucina pers. obs.).
Distribution and habitat
Gazania spendidissima is endemic to a narrow strip of the west coast between Port Nolloth and Hondeklipbaai in the Northern Cape Province.
Derivation of name and historical aspects
This species was first collected by Neville Stuart Pillans at Port Nolloth in October 1924, but it had remained largely unnoticed and new to science until described very recently by Magee et al. (2011). The specific epithet spendidissima refers to the splendour of the plants in flower, largely due to the striking contrast between the greyish semisucculent leaves and the large golden-yellow or orange flowers.
The plants grow in deep sands where they are at risk of being buried. They are usually found between the upper beach and adjacent coastal dune systems, receiving some salt spray during stormy and windy weather. They can be distinguished from the other species of Gazania Gaertn. by the subshrubby growth habit, the semi-succulent leaves which are greyish on the upper surface, and in particular the prominently maculate involucre formed by the bristle-like hairs with black bases.
Uses and cultural aspects
There are no recorded uses for this species.
Growing Gazania spendidissima
Gazania spendidissima is ideal for coastal gardens and should be planted in full sun where the flowers will stay open for most of the day. In partial shade the leaves lose their striking greyish colour. Although this species has yet to be introduced into cultivation it is likely that it will be easily propagated from seeds as are the other species of Gazania (see Gazania krebsiana).
