Coop Scoop- Jimson weed is a type of Datura, except these have big flowers and the only thorny part is the seed capsule. This is a Moon Flower or Devil's Trumpet. Scientific name is Datura Stramonium. They are poisonous, but worth it, if you don't have curious kids! Mine are old enough to know it's bad, so they just enjoy the amazing fragrance and the novelty of it blooming at night. Datura Inoxia are my favorite. I think they have bigger flowers and a better fragrance!
Peggy- I planted some double and triple yellow and purple and none came up. I've heard they aren't as fragrant? This one is already wafting nicely, and it's not open all the way. Kind of a lemony honey scent. YUMMMMM!!!!!
