Rudbeckia irregularities

With so many dozens of black-eyed susans in our garden, we were bound to spot some flowers that didn’t grow quite perfectly. Here are some examples.

One petal that remained fused:

black-eyed susan in bright sunlight, the petal at the 3 o'clock position looks a bit like a cornucopia

Irregular center disks:

the brown center has eight growths, some pointed and some flat, around the circle, and a thin, curvy yellow growth out the middle

cone-shaped center disk, with a smaller one pointing to the left growing out of the left side

two cone-shaped centers on one flower, mostly connected but separated near the top

Another type of irregular center, a condition called fasciation that causes elongated growth that’s usually in the stem, which causes the flower to be elongated too:

a really large roundish center that's about double the normal width, with petals hanging below and a couple petals strangely growing out the top right

(I left this flower in the garden, since fasciation is not contagious.)

Aster yellows, an incurable condition caused by a bacteria that’s spread by leafhoppers:

black-eyed susan with narrow petals that are light green instead of yellow

six brown centers without any petals

(These affected sections of flowers were removed, because aster yellows is contagious.)

Curled petals that seem to be caused by the tear / hole near the tips:

yellow flower with some narrow red in the center of the petals, all but three of the petals curled under, viewed from above

It’s a pretty effect, but it happened to many flowers, so I’m curious whether it’s something to be concerned about. I haven’t been able to find any information about this yet.
