Tobacco plants (Nicotiana alata) come back each year stronger than the previous year. They are one of the re-seeding annuals that adapts to the specific conditions of where they grow. This one fills the air with a beautiful scent when the sun sets. It also glows in the dark. I have it seeded in the far back border of my backyard garden. I almost always have to trek out to smell them before I go to bed.
