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.

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?
