Hi,

I've been growing a few different species of Datura and Brugmansia for a couple years now. The first few years growing Datura Wrightii it was extremely fragrant. As soon as I would walk outside at night I could smell the flowers. All of a sudden last year, and now this year, when they bloom they barely have any fragrance. Its a little sad. The only thing that I can think of that caused this is maybe having too many species mixed together/cross polination? Is it time to find seeds from somewhere else? or do I need to add something to the soil?
