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:
Irregular center disks:
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:
(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:
(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:
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.
