Nicotiana alata. This flowering tobacco stands regally in the garden at 1-1.5m (3-5′) tall, with a cascading head of pure white, tubular flowers that attract moths and hummingbirds. It looks splendid among other tall flowering plants such as Agastache and foxgloves. Grow Jasmine Tobacco Nicotiana seeds in a warm spot in your garden, in full sun. Pollinated by moths, this Nicotiana’s flowers become particularly fragrant after dusk, so plant some near a window and let the scent waft in during summer.
