there are different types of Yesterday, today, and tomorrows, the one i am talking about is Brunfelsia grandiflora, very beautiful and extremely fragrant. you can smell it from far away. its flowers open the first day dark purple, the second day they are a light purple, and the third and last day they are white. its so beautiful, this multicolored bush! i have two in my garden.
Eeeek!! In the Solanaceae family! Deadly, my tongue, then my throat would swell, and I'd choke to death, no joke! My sensitivity to nightshades has become ridiculous. I sniff nothing that I do not know absolutely for sure that is not a night shade.
Sheesh, used to be just tomatoes, peppers and potatoes. But I lived someplace that had a tree that had blooms constantly. and they smelled like Lilacs, which I miss. I got sicker and sicker, bummer.
