I have several fasciated tomato plants this year. I have 30 varieties planted in earthboxes, and I have spotted at least five so far. Several have fasciated stems. My cherokee purple has a fasciated blossom. It's crazy.

Second angle of that fused stem, truss and blossom.
Close up of the fused megablossom and truss. Should I cull it?
