    History and curiosities: 

    The scientific name, Magnolia grandiflora, consists of the genus name Magnolia, in honour of Pierre Magnol (1638-1715), botanist and botany professor in Montpellier, and the Latin term grandiflora, "of big fowers", formed by grandis, "big", and flor, "flower".

    The first identified species of this genus was the sweetbay magnolia (Magnolia virginiana), found by missionaries in North America in the 1680s; by the 18th c. XVIII it was found the bull bay (Magnolia grandiflora),which in 1726 was brought to England by the botanical collector Mark Catesby.

    Both the bull bay and its flower, the magnolia, are symbolically very binded to Southern United States: the bull by is the state tree of Mississippi and the magnolia was, in the American Civil War (1861-1865), the Confederate States Army's emblem and nowadays it is the national flower of Louisiana and Mississippi.

    In Barcelona, it can be found at urban green spaces and historical gardens, as well at streets, as Gran de Gràcia street.
