Dawn Spencer Hurwitz Pink Gardenia: In the Beaux Arts line, with notes of bergamot, gardenia, tuberose, ambergris and musk. It starts very light, with a touch of bergamot. The gardenia note comes on next, but stays very soft and low, then fades into a tuberose blend with a warm musky dry down. Much softer than all the white flowers might lead you to assume, and nicely done, although I prefer her Nouveau Gardenia.
Pas Simple Light Gardenia: This one has notes of gardenia, hibiscus, hyacinth, ginger, musk, citrus, and cedar. The top notes are very grassy and green; it dries down to a subtle tropical fragrance with a hint of gardenia — no heady white flowers here — and a persistent clean note that reminds me a bit of dryer sheets. They also make a Dark Gardenia, but I have not tried it.
Montale Intense Tiare: I don't know what notes this has, but it smells mostly like monoï, which is made by macerating Tiare (a variety of gardenia) petals in coconut oil. It starts very strong and sharp, with just a hint of coconut; over the next few hours, the coconut intensifies, and the gardenia gets softer and warmer. Smells just like a tropical vacation, and the lasting power is excellent.
Floris Gardenia: Floris describes this as "fresh green fruity top notes, blended with a floral heart of Gardenia, Lily, Cyclamen, Tuberose and Jasmine, with warm base notes of Sandalwood and Labdanum to ensure a well blended and lasting accord." The top notes are in fact very green and fresh; the gardenia is very light. The fragrance warms up on the dry down, and is pretty, but a little flat.
Isabey Gardenia: The notes are tangerine bark, ylang-ylang, orange flowers, gardenia, Bulgarian rose, jasmine, iris, musk, ambergris, and sandalwood. This is a 1920s fragrance, reissued by Panouge. I have no idea how close it is to the original, but it has a classic, old-fashioned feel. It starts with gardenia, sweeted by ylang with light citrus and orange blossom, and settles into a rich, deep floral with lots of jasmine. The dry down is smooth and creamy with the tiniest hint of powder from the iris. A really beautiful perfume with a price tag to match ($240 for 50 ml at luckyscent, or €365 for a limited edition bottle of extrait at first-in-fragrance).
