Jasminum officinale L. - common jasmine, poet's jasmine, jasmin, **(Echter) Jasmin**

Twining deciduous shrub, native to western Asia, commonly cultivated and naturalized; leaves opposite, imparipinnate; flowers white, with heavy sweet scent. [[http://www.efloras.org/florataxon.aspx?flora_id=5&taxon_id=200017787]]

"The essential oil of Jasminum officinale is used in aromatherapy. Jasmine absolute is known as the 'King of Oils', and its heavy, sweet scent is loved by most people. The flowers release their perfume at dusk, so flowers are picked at night and a tiny amount of oil is obtained by solvent extraction. The result is a very expensive oil, but it can be used in low concentrations so it is not that uneconomic to use it in products." [[http://en.wikipedia.org/wiki/Jasminum_officinale]]

"The perennial jasmine plants that grow outside in warm regions are grown inside as greenhouse plants in northern climates. Poet's jasmine is much more cold tolerant than royal jasmine, and cultivated jasmine plants are usually grafted onto poet's jasmine rootstocks."

"Taxonomy of J.officinale var.grandiflorum: J. officinale subsp. grandiflorum is mainly referred to as [[jasminum_grandiflorum_l|J.grandiflorum L.]] [5,23]. According to the literature, J. grandiflorum was grafted onto J.officinale  L.  stalks in France to obtain a frost-resisting jasmine variety [3,24]. From a botanical standpoint, this suggests that J.grandiflorum and J.officinale were/are two distinct species. However, according to actual taxonomic literature, this seems not to be the case [25]. Also, previous taxonomists treated J. grandiflorum as either a variety [J. officinale var.grandiflorum (L.) Stokes, (1830)] or a forma [J.officinale forma grandiflorum (L.) Kobuski, 1932] of J.officinale [25a], clearly pointing to only one species." \\
