Mutation in "Goldsturm" Black-Eyed Susans
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? FayeC zone 5a |

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" seeds. -paghat the ratgirl -- "Of what are you afraid, my child?" inquired the kindly teacher.

Mutation in "Goldsturm" Black-Eyed Susans
If you planted them from seed, they are NOT pure Goldsturms. They are
strains. Goldsturms only propagate through cuttings. In order to get viable seed, they have to be hybridized with other types of Rudbeckia. The flowers you end up getting from these are Goldsturm hybrids. They resemble Goldsturms, but they are not the "true" Goldsturm. The flowers on these plants WILL show mixed blooms. Examine the seed packets for these and they should say "strain" on them someplace. "Faye Tarzwell" wrote: I have a few patches of "Goldsturm" Black-Eyed Susan and they have bloomed for 2 years now.

Mutation in "Goldsturm" Black-Eyed Susans
What surprised me was that the patch the new one was in had grown last year
and there was no red in them... I grew mine from the Mackenzie seeds (hirta variety). Thank you for your explanation and I love your site and all the pictures )) FayeC zone 5a "paghat" wrote in message news In article , "Faye Tarzwell" wrote: I have a few patches of "Goldsturm" Black-Eyed Susan and they have bloomed for 2 years now.
