As the name suggests, sweet pea is sweetly fragrant when blooming in spring. It's also quite ornamental, thanks to the brightly hued pastel flowers of pink, purple and white. Give it something to ramble on and put it where you can enjoy the scent—by a garden gate or doorway, for instance. Sweet pea (Lathrys odoratus) is an annual vine growing about 3 feet tall.
