Tunisia is the world's leading producer of orange blossom. The bitter orange tree was introduced to the Mediterranean in the Middle Ages.
The essence of its flowers – neroli – is sublime eau de Cologne and perfumes. In France, guests of the Château de la Treyne, screwed onto its rock above the Dordogne river, have a full experience. The fertile landscapes of Reunion where ylang-ylang grows. From the cinnamon gardens of Sri Lanka to the Laotian jungle populated with Siamese benzoin.
