Definitely! I would love to grow some kind of super-fragrant tobacco for frags. And I do have lilac bushes that are mega-fragrant - it might be cool to try to create a small quantity of essence from them.
I've especially toyed with the idea of getting the citrus-like scent from the black walnuts in our yard - we have bushels of the damn things every year. Unfortunately, they give off a toxic substance as well, and it's too much of a pain to separate, really.
So yes - I think that sometimes scent brings out my inner farmer.
