jasmine blossoms in a dish of water
Yesterday I plucked fat, unopened Jasminum sambac buds (Maid of Orleans) and floated them in a small dish of water. I've read about it but have only tried it before with flowers that had already opened. In the evening they started opening but the scent wasn't that strong. I kept them by my bed and I could smell them during the night but the real treat came this morning when I discovered how intensely scented they became!
I highly recommend this method if you haven't already tried it.
