Just chiming in til someone who knows what they are talking about replies :)

I bought a Jimson Weed plant this year to try out. No scent. Purplish flowers. Looks similar to what I had, but I ended up tossing it.

My neighbor gifted me her 2 dat Metel Black currant purple swirl plants just before the frost hit. They have a slight lemony scent. Is this the fragrance you were referring to? I cut them down and they are in my basement for the winter.

Kasha, that looks like the one I originally had in my garden. I just remember the scent being almost intoxicating around dusk. I vowed to plant them all around my deck and screened in porch, only I obviously got the wrong seeds.

The photo is the one that had the fabulous scent. I'm thinking it's like yours...
