I just went out and checked these plants over after looking up info on this virus. If it is TBV, it's possibly just the one plant, so far. The others of the same variety don't show the pink streaking.
Plant A
Plant B
In my ignorance, I just thought that plant B was the first that bloomed and those blooms were just more advanced than the others.
Plant B
is in the shadiest spot; parked behind the others, and this area gets just a bit of morning sun, and about 4 hours worth of afternoon sun.
All of the rest of the plants of this variety look just like Plant A, and all of the plants, including B, have leaves that look perfect. As least as much as any in my presently dried out gardens.
