Daisy-like, they are part of the Asteracae family. They grow a few inches in height and take a few weeks before blooming. Gazanias are natives of South Africa. They are generally low maintenance and grow well in full sunlight and water.
While searching for more information on the flower and it's origins I came across an interesting link which talks about the derivation of the name - Gazania.
The generic name Gazania, was given in honour of Theodor of Gaza (1398–1478). He was responsible for the translation of the botanical works of Theophrastus from Greek into Latin. Another possibility is that gaza is Greek for riches and could refer to the richness in colour, variety and abundance of the plant.
