It took me a while to figure out exactly what
@HamiltonSquare was trying to convey.
The banner is labeled as Symphyotrichum dumosum Sapphire Mist and what looks like the original image is correctly in that same database entry
Aster (Symphyotrichum dumosum Sapphire Mist)
but the discussion thread is actually linked to
Bushy Aster (Symphyotrichum dumosum 'Sapphire') when it should be listed under the 'Sapphire Mist entry.
If I were to delete the suspected duplicate 'Sapphire' entry, it would also erase that banner link thread.
Let's see if it's something
@dave can correct.
