Pericallis cruenta (syns. Senecio cruentus and Cineraria cruenta) is a species of flowering plant in the family Asteraceae, native to La Gomera and Tenerife islands of the Canary Islands.[1] It has a non‑woody growth form and is typically found growing in Tenerife's laurel forests.[2]
With Pericallis lanata it is a parent of the widely cultivated garden plant Pericallis × hybrida, the florist's cineraria.[3] In the past, and continuing today, there has been confusion and debate about the identity and origin of Pericallis × hybrida, with Pericallis cruenta being incorrectly called a 'feral' form of the florist's cineraria.[4][5]
In 1895 in a series of letters and articles in The Gardeners' Chronicle and Nature, William Turner Thiselton-Dyer argued that the garden plant Cineraria cruenta was derived by simple breeding from the wild plant Senecio cruentus, while William Bateson argued that it was of hybrid origin.[5] The argument was resolved by Bateson, who enlisted Richard Irwin Lynch, Curator of the Cambridge University Botanic Garden, to do some experimental crosses in 1897. Published in 1900, the results showed that the garden cineraria is clearly of hybrid origin.[5] In fact, members of the genus Pericallis had been brought to England in 1777 and 1780, and by the early 1800s had been extensively hybridized by horticulturalists.[4] By the time of the debate, there were numerous cultivars displaying wide morphological variation.[4][5]

Pericallis cruenta, ook bloedkruiskruid genoemd, is een plantensoort uit de composietenfamilie (Compositae of Asteraceae). De plant is endemisch in de vochtige streken van het noorden van het Canarische eiland Tenerife. Ze komt daar vrij algemeen voor op de hoogte van het laurierbos. De soortsaanduiding cruenta komt van het Latijnse woord cruentus (bloedrood) en verwijst naar de donkerrode kleur van de plant. Door de bewoners van Tenerife wordt de plant "tusílago morado" genoemd.
Pericallis cruenta is een rechtopstaande, 0,3 tot 1 m hoge, overblijvende, kruidachtige plant. De plant heeft eironde tot hartvormige wortelbladeren met een ingesneden, dubbel getande bladrand. De bovenzijde van het blad is donkergroen en behaard, de onderzijde is meestal karmijnrood en grijs viltig behaard. De stengelbladen hebben een geoorde, half-stengelomvattende voet. De bloemhoofdjes zijn ongeveer 2 cm breed en bestaan uit een hart van purperen buisbloemen en een krans van 7 tot 20 lichtpurperen straalbloemen. De omwindselblaadjes zijn kaal of pluizig behaard. De buisbloemen hebben vijf kroonslippen. De bloeitijd is van april tot mei.
