GAZANIA FLOWERS: A POPULAR HEARTY PLANT
Its classification is:
Kingdom Plantae
Order Astales
Family Asteracea (this is the daisy family)
Genus Gazaania
Species G. rigens
Gazania belongs to a family that is native to southern Africa, namely South Africa and Mozambique.
Many of the species of this plant are hard to distinguish from one another; therefore, the number species varies widely depending on the specialist worker. In 2009, a much-needed molecular phylogenetic analysis revealed that many of the so-called species of this plant are not really separate from one another. They form a species complex, consisting of about 16 recognized living species (Howis et al., 2009). The flowers of these plants come in various colors, with yellow and orange shades being the most common.
Gazania flowers are easy to grow. They thrive as ground-cover, when growing in full sunlight. A single plant can live for several years because Gazania is a perennial plant. They “come back,” year after year, via their seeds (“it reseeds” itself). They are hearty and drought-tolerant, and they prefer low altitude, temperate regions. They only rarely live in tropical areas.
Their flowers “close” up at night and during cloudy days. The abundant petals on the flowers have a dark starburst or ring pattern of black dots surrounding their golden center.
If ingested, all parts of this plant are poisonous to humans. Nevertheless, herbivores, like rabbits, squirrels, and deer eat them.
The fossil record of this plant is poorly known. Apparently, it dates to to Pleistocene time (Willis and Niklas, 2004).
