Vegetative characteristics

Gerbera species and varieties are perennial herbaceous plants . There are rhizomes designed as Überdauerungsorgane.

The leaves stand together in basal rosettes. The parchment-like to leathery leaf blades are obverse-lanceolate, oblong, obovate, ovate or almost circular and pinnately lobed, pinnate, pinnate or mostly simple. The leaf margins are wavy, serrated to serrated. The leaves can be hairy or bare.

Generative characteristics

For each leaf axil, a single, terminal, cup-shaped inflorescence is formed on a slender inflorescence stem that has no, few or many bracts ; There is rarely more than one flower head in a leaf axil.

The involucre is inverted conical to broadly bell-shaped. There are two to three or more rows of bracts that overlap like roof tiles. There are no leaves of chaff on the flat, bare flower head base . All flowers in the flower head are fertile. There are a number of external flowers that are purely feminine; mostly they have staminodes . The inner flowers are hermaphroditic or functionally masculine. The corolla tube ends with two lobes.

The stem-round or spindle-shaped achenes are four to ten ribbed and bald or finely haired. The pappus consists of rough bristles.

The number of chromosomes is 2n = 46 or 50.

Systematics and distribution

The genus Gerbera was established in 1758 by Carl von Linné in Opera Varia in quibus continentur Fundamenta Boatica, Sponsalia Plantarum, et Systema Naturae 247. Synonyms for Gerbera L. nom. cons. are: Gerbera sect. Piloselloides Less. , Atasites Neck. , Berniera DC. , Lasiopus Cass. , Piloselloides (Less.) C. Jeffrey ex Cufod.

The genus Gerbera belongs to the tribe Mutisieae in the subfamily Mutisioideae within the family Asteraceae .

The distribution of the genus Gerbera is purely ancient . The 30 or so species are mainly found in Africa , Madagascar and tropical Asia . Most of the species (18 species) are found in South Africa (only a few species occur only in the Capensis ). There are eight species only in Madagascar and in 2011 around six species are still common in Asia.

Horticultural history of gerberas

Before 1737 the gerbera was known as the African / Ethiopian aster; In 1737 it was described for the first time by the Dutchman Jan Frederik Gronovius and was named "Gerbera" in honor of the medical doctor and botanist Traugott Gerber (1710–1743). A year later, his friend Carl von Linné included the species in his system.

In 1884 Robert James, a plant trader from Durban, South Africa, found the species in the gold fields of Barberton in the Transvaal . He donated the "Barberton Daisy", the Barberton daisy, to the Botanical Gardens in Durban ; whose leader recognized it as the gerbera. In 1886 the first specimen of herbarium was brought to the royal garden at Kew near London. In 1889 the first gerberas were registered, described and presented to the public. This first scientific description is from JD Hooker in Curtis Botanical Magazine . He describes the South African "Barberton Daisy" (today Gerbera jamesonii ).

In 1890, Irwin Lynch made his first attempts at crossbreeding at Cambridge Botanical Gardens. In 1893 the gerberas came to Germany, the first gerbera plant was cultivated by Ferdinand Friedrich Haage in Erfurt .

Gerbera varieties are not hardy.

The gerbera is one of the most popular cut flowers worldwide. Since the 1990s, some varieties have also been offered as indoor plants .

In 2009 dealers began to offer a group of gerbera varieties that are hardy in areas with little frost (Garvinea ®). However, it can only hibernate outdoors at temperatures down to -5 ° C.

The numerous breeds are mostly crosses between Gerbera jamesonii and other South African gerbera species such as Gerbera viridifolia . The intersections are Gerbera - hybrids called.

Use as a cut flower

To stabilize the stem, the stems of the gerbera flowers are wrapped in a spiral with a floral wire that is pierced into the top of the flower head or it is stabilized in another way. Gerbera go well with other cut flowers in vases.
