Default Mutation in "Goldsturm" Black-Eyed Susans

In article , "Faye Tarzwell"

I have a few patches of "Goldsturm" Black-Eyed Susan and they have bloomed
for 2 years now.
I planted them in the spring of 2002 from seed (McKenzie seeds).
This year I noticed that one patch had a slightly mutated version of the
"Goldsturm" Black-Eyed Susan. It was the same flower shape but the petals
were half yellow (edges) and half red.
Anybody heard of such mutation?

Goldsturm seeds do not grow true. Most of us who have "Goldsturm" cannot
always be totally certain we have the real deal, unless knowing the
grower, & that they were started from stem cuttings (or from spring
division of one's own known "Goldsturm"). Seeds from Jelitto or Behnke &
elsewhere are "approximations" only. When the seed producers are
criticized for this, they shrug it off as their good & honest intennt to
produce seeds commercially that will result in plants "nearly uniform" or
"pretty close" to Goldsturm -- that's their goal, & that's why they call
them "Goldsturm." But the reality is you can never be certain what will
grow from these seeds (if gotten from actual "Goldsturm" stocks) & anyone
claiming stronger uniformity is probably selling the wild Sullivant's
Rudbeckia, a subspecies, falsely labeled "Goldsturm," as the wild
supbspecies seeds ARE apt to be uniform.

The unpredictability of what grows from these seeds MIGHT conceivably
result in something that's actually a sport worth saving & developing
(rather than just the usual reversion to the lankier wild subspecies), &
since the petals on yours are half red, that might indeed be the rare
"something" worth working with to preserve. But to me it sounds like
you're describing a completely different cultivar mixed into the packets
from carelessly sourced & intentionally mislabeled pseudo "Goldsturm"

"Oh, sir! The flowers, they are wild," replied the timid creature.
