Magnolia champaca seed
The flowers from this
Michelia flowers produce in great quantities. On a warm humid night, the scents can easily be enjoyed several hundred feet away. If you drive near by, you will notice the scent immediately.
These are flowers you don't have to "stick your nose in" as the scent exudes from the tree. However, you really can't STOP sticking your nose into a over and over again.
Also you could take the flower, home made natural perfume, into car, office, rest room, and anywhere you want fragrant atmosphere.
