Gazania rigens

Botterblom

Species Card Details

Importance:

The species is of global importance in horticulture and is a common, ecologically important coastal dune and rock pioneer species on the southern and eastern South African shoreline. Genomic information is vital for future breeding of ornamental Gazania cultivars and to unravel the taxonomy, cytology, evolution, genetic diversity and biogeography of Gazania.
