Depending on one's point of view, 1 March could be seen as the start of spring. I know that strictly speaking spring starts at the spring equinox, I think, or somewhere around 21 March, but I am impatient for spring, so I will choose 1 March, so there!
Anyway, what perfume could be more appropriate for spring than Hermes Eau D'Orange Verte?
Released many years ago (1979 according to Basenotes), this lovely perfume has notes of mandarin, sweet orange, mint, lemon tree extract and bitter orange. I have seen notes like patchouli and papaya mentioned as well, but to me it is a very orangey perfume, with a light woody dry down. Eau D'Orange Verte is a light cologne-like perfume, so don't expect stellar lasting power. However, I can't think of much more joyful and uplifting than that first luscious citrus burst. It sings off the skin with exuberance and happiness, perfect for bolstering spirits after a long winter.
There is also a concentre version around, which I have tried, but not often. My vague recollection is that it is a bit denser than the original, with less zing and zip, but both are very nice.
