It sounds<br \/>\nlike it could be <em>Datura metel<\/em>, which is grown as an annual. <em>Datura<\/em><br \/>\nblossoms point up or outward, while <em>Brugmansia<\/em> is shrubby, and its flowers hang downward.<br \/>\nSome <em>Brugmansias<\/em> will overwinter in the Seattle area and are<br \/>\nsemi-evergreen or evergreen. Others may die back to the ground and come<br \/>\nback in the spring. They are longer-lived than <em>Datura<\/em>. <em>Datura<\/em> is more<br \/>\nlikely to act like a perennial or annual.<\/p>\n<p>If you are growing an annual <em>Datura<\/em>, the best thing to do is save<br \/>\nseed from the fruit capsules in summer. Exceptions are <em>Datura wrightii<\/em><br \/>\nand <em>Datura inoxia<\/em>, which can overwinter. In warmer winter climates, these<br \/>\ncan be covered in the fall with twigs, straw, or pine needles. Growth may<br \/>\nresume in March or April. In colder winter climates, you would need to<br \/>\noverwinter the fleshy rhizomes in a container, covering them with earth.<br \/>\nKeep the container in a cool, dark garage or cellar. Expose the<br \/>\nrhizomes to temperatures of 53-64 degrees and daylight beginning in<br \/>\nMarch. This is much more difficult than simply planting new seed each<br \/>\nyear, but plants which sprout from rhizomes grow faster and flower<br \/>\nbetter.
