Carrot family

A large, readily identifiable family with many well-known culinary and medicinal species. The alternative name, Umbelliferae, refers to the conspicuous umbellate compound inflorescence typical for the family.


This is a cosmopolitan family with increased diversity in temperate regions, particularly in the northern hemisphere. Within southern Africa, the Western Cape and the eastern escarpment show the highest diversity in species.

Growth forms

Mostly herbaceous annuals, also biennials or perennial herbs and trees. Many species have basal rosettes but others may be stoloniferous or even cushion plants.


Found in grassland, fynbos, open scrub, forest and moist places next to streams and rivers; some real aquatics, but also in dry environments.

Flagship species

Heteromorpha arborescens (parsley tree; wildepietersieliebos [A]; umbangandlala [X, Z]) is a shrub or small tree with glossy leaves. Dried, hollowed stems of this plant are used by the Xhosa as musical instruments. In folklore it is planted at the gathering places and kraals of chiefs to ensure loyalty towards the leader. It is medicinally used to treat abdominal pains. An infusion of leaves is used to deworm children and infusions of roots are used for coughs and dysentery. The smoking of dried plants is said to relieve headaches. (Photo: NC).


Significance of the family

This family is an important food source as the leaves, stems and roots are utilised, e.g. carrots (*Daucus carota). Many are used as culinary herbs, e.g. parsley (*Petroselinum crispum) or as spices, e.g. coriander (*Coriandrum sativum). Many species have herbal and medicinal properties and the essential oils of some are used in the perfume industry. Some genera (*Eryngium, *Astrantia, Bupleurum and *Ammi) are cultivated for the flower industry and others as ornamentals for their architectural inflorescences.
