Nicotiana glauca, also known as tree tobacco, is a unique and fascinating plant species with a rich history of medicinal and cultural uses. Native to South America but now found on other continents as an introduced species, it grows to heights of more than two meters and has large blue-green leaves attached to the stalk by petioles. While highly toxic if ingested, the plant has been used by Native American groups as a poultice to treat various ailments. It is now being investigated for use as a biofuel. If you're interested in growing this hardy plant, it prefers a well-drained deep rich moist soil in a sunny position and requires more than 14 hours daylight per day in order to induce flowering.
