Many different guava cultivars have been propagated in the Cape. These were planted and only the best trees were selected for cultivation. The hybrids developed were named after the farmers who cultivated them. This gave rise to names such as Malherbe, Rousseau, Du Preez, van Zyl, and Faan Retief. Although new cultivars are continually being tested, the pink flesh of the Fan Retief cultivar, created in the Western Cape, currently accounts for 90% of commercial plantings.
