Strelitzia /strɛˈlɪtsiə/[3] is a genus of five species of perennial plants, native to South Africa. It belongs to the plant family Strelitziaceae.[4]Acommon name of the genus is bird of paradise flower/plant, because of a resemblance of its flowers to birds-of-paradise. In South Africa, it is commonly known as a crane flower.
Two of the species, S. nicolai and S. reginae, are frequently grown as houseplants.[5] It is the floral emblem of the City of Los Angeles and is featured on the reverse of the South African 50-cent coin.
The genus was named by Joseph Banks in honour of the British queen Charlotte of Mecklenburg-Strelitz.[6][7]
The species S. nicolai is the largest in the genus, reaching 10 m (33 ft) tall, with stately white and blue flowers;[8] the other species typically reach 2.0 to 3.5 m tall, except S. caudata, which is a tree of a typically smaller size than S. nicolai.
The leaves are large, 30–200 cm long and 10–80 cm broad, similar to a banana leaf in appearance, but with a longer petiole, and arranged strictly in two ranks to form a fan-like crown of evergreen foliage.
The flowers are produced in a horizontal inflorescence emerging from a stout spathe.
They are pollinatedbysunbirds and blue-faced honeyeaters, which perch on and drink from the spathe. The weight of the bird when standing on the spathe opens it to release the pollen onto the bird's feet, which is then deposited on the next spathe it visits. Strelitzia species lack natural insect pollinators; in areas without sunbirds, plants in this genus generally need hand pollination to successfully set seed.[9]
Five species are recognised, although one—S. juncea—has been shown to be genetically nested within another, S. reginae. It is possibly a mutation that is in the process of speciating.[10]

Plants in the genus Strelitzia produce no wind-borne pollen, and have an OPALS allergy scale rating of 1, meaning a very low risk of causing allergic reaction.[9]
Strelitzia is also the name of the botanic journal of the Pretoria-based National Botanical Institute,[12] which has since been converted into the South African National Biodiversity Institute (SANBI). The Strelitzia journal replaced Memoirs of the Botanical Survey of South Africa and 'Annals of the Kirstenbosch Botanic Gardens.[13]
