Countries that have cultivated mimosa for the perfumery trade include Morocco and India, but the Vallée du Tanneron is where the mimosa processed in Grasse comes from. The harvest season lasts for about four weeks (February to early March) and is subject to climatic conditions. Frosts and snow can influence the plant's yield as can a dry summer, which can affect the flower bud growth.
Initially the enfleurage technique was used but the concrete is now obtained with volatile solvent extraction. To obtain 1kg of mimosa concrete, between 110kgs and 125kgs of mimosa flowers (and twigs) are required. The yield for the absolute is approximately 30%. Annual production of mimosa concrete fluctuates between 200kgs and 1.5 tonnes, according to weather conditions, including frosts and other extremes. Last year was a very good one for mimosa production, but although the 2006 harvest is now in its quality is not yet known.
The mimosa absolute is described as floral, powdery and green, and it also has a delicate watery quality.
It is used in cosmetics and soaps and has also been linked with many fine fragrances.
The sunshine quality of mimosa is evidenced in L'artisan Parfumeur, with Mimosa pour Moi, by Molinard Jeune with Le Mimosa and by L'Occitane with L'Eau d'Azur.
Fragrances in which mimosa plays a vital part, but is not the main theme of the fragrance, include Farnesiana by Caron, Chanel Nº 5, Moment Suprême by Jean Patou, Casaque by Jean d'Albret, Kalispera by Jean Desses, Masumi by François Coty, Paris by Yves St Laurent, Byzance by Rochas, Amarige by Givenchy as well as Summer by Kenzo.
A scent which truly celebrates mimosa is Champs Elysées by Guerlain, where the leaf extract features in the top note and the bloom plays a major part in the heart structure.
The yellow flower is the star of the remix of Givenchy’s Amarige in the context of its Exclusive 2005 Harvest collection. Originally created in 1991, the juice has been reworked to showcase mimosa harvested in Grasse in 2005. The original scent's juice comprises top notes of mandarin leaf and orange blossom, followed by mimosa, jasmine, ylang-ylang and gardenia notes. The new version features the green sensation of the 2005 mimosa harvest in its top notes along with notes of orange blossom. Heart notes highlight the mimosa absolute's rich and radiant quality, while the base notes of the juice accentuate the blossom's powdery aspects. Mimosa makes up about 25% of the new formula, compared with about 10% in the original, providing a true ode to mimosa and the luminosity of spring.
