Number One Intense Perfume by Nicolai, Although composed predominantly of floral notes, number one intense drifts toward the green side of a natural garden, allowing this fragrance to fit in nearly anywhere. The top notes include galbanum and tagetes with a splatter of black currant. The heart is overwhelmingly tuberose with touches of ylang-ylang, jasmine, orange blossom and rose with a side of black currant leaf.
