\"\"<\/a>I was sitting at my breakfast table this morning thinking ‘what plant should be next for #AdventBotany2018″?\u00a0 The rich smell of the blue hyacinth in front of me was filling the room when I had one of those ‘you idiot’ moments – er, have we done hyacinth yet?<\/p>\n

Hyacinths are grown both for their large and bright flower heads and for their scent.\u00a0\u00a0<\/p>\n

Hyacinth odour<\/h2>\n

The scent of hyacinth flowers can be analysed by capturing the chemicals in the air around the flowers, known as headspace analysis.\u00a0 Brunke et al. (1994) identified at least 40 different components of hyacinth odour.<\/p>\n

\"\"<\/a>
Headspace analysis of hyacinth odour (Brunke et al. 1994)<\/figcaption><\/figure>\n

But which of these 40 compounds matters?\u00a0 It might be reasonable to assume that the major components of the smell are those present in the highest quantity but this is not the case.\u00a0 Our noses have quite specific sensitivities so quite rare compounds can sometimes have an undue influence on the overall scent.\u00a0 Recent reports on hyacinth scent suggest three main compounds are key:<\/p>\n\n

So, when sniffing your hyacinths, think about that heady combination of ethyl 2-methoxybenzoate, ocimenol and cinnamyl alcohol and appreciate the challenging work of biochemists in the unravelling of this heady Christmas aroma.<\/p>\n
