Brugs and daturas can be crossed but it is rare and the results of someones careful work,usually in a lab.There was a prominent member of the brug community that claimed to have crossed them a few years back.I grew some of her seed and they were dats in every way.
None of the very few crosses done have resulted in anything worthwhile.
Now,some brugs do have upward facing buds.El Dorado comes to mind.The buds face up and the blooms finish in a horizontal position.
