 "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]]
-"Harvest time did not affect the quantity of jasmine concrete extracted from the jasmine flowers. However, harvest time significantly affected the chemical composition of the jasmine concrete. The concentrations of indole and cis-jasmone compounds that characterised jasmine oil, were higher in the jasmine concrete obtained from morning-harvested flowers compared to the evening-harvested flowers. As such the quality of jasmine concrete obtained from morning-harvested flowers was better than jasmine concrete obtained from evening-harvested flowers. Jasmine concrete extracted from flowers harvested in the morning also contained higher concentrations of the following aroma-bearing compounds, benzyl alcohol, linalool and benzyl acetate, compared to concrete from evening-harvested flowers. Aroma-bearing compounds such as eugenol, benzyl benzoate, farnesol, methyl palmitate and methyl salicylate showed higher concentrations in the jasmine concrete obtained from evening-harvested flowers. Morning harvesting of jasmine for oil extraction is recommended." \\
+"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."
