So dramatic. Poisonous, datura can grow to 4+ feet tall in full sun but in my more shady garden the branches tend to spread to a width of several feet. The dramatic, 6 inch blooms are white trumpets which flower either morning, evening, or all day in the shade. The fragrant flowers eventually produce a spinney seed pod. A perennial in zones 6-11. Treat as an annual elsewhere. G21-60 (be patient) 20 seeds.
