      This plant was not one of our subjects but is showing regrowth following an earlier harvest.
      Those are not yellow flowers but are floral remnants after the petals were eaten by something.


      A look at one of our control plants shows a similar picture.

    The same plant had been harvested by someone when we visited in 2018
