Lots of information and things to think about, Lorn. I will have to look for a dark red/purple trumpet for sure. Also, I will give a closer look at some cross sections of these flowers especially on those whites with the red centres.
I wondered when I saw a couple asiatic seedlings bloom this year if it was SORT OF the same thing happening as that which happens in the black hearted aurelians. With these asiatic seedlings (one pictured below) which have green hearts and then develop red over the green as the flower ages giving what appears to be a black heart. I did cross two similar seedlings just to see what their seedlings would give - more black hearted seedlings??
