Reading your profile, the perfume house Dyptique came to mind (I believe they have a store in SF, or perhaps at Barney's there). They make clean, often crips, very natural smelling perfumes based on things like herbs and flowers. Clean yet complex, avoiding the excessive simplicity and shallowness of many supposedly natural perfumes. Eau Lente is one example, but the whole line is worthy.
For something before you go to SF, I'm thinking about certain Guerlains (usually available at either Saks or Neiman) related to your statement of "flowers, early mornings": Apres l'ondee (which means "after the rain", and really reminds me of flowers after the rain), or Chamade, a very serene floral (you have to wait for the spectacular drydown, though).
