Aster Yellows had become a "thing" in my garden (and most of the Midwest if not everywhere) I have wondered if fasciation and Aster Yellows were in cahoots, since dandelions are certainly in the Aster family. It seems they are not related. Not all mutants are related, I guess.
Did you know some plants are bred for their tendencies to fasciate? It's true! Think of Cockscomb Celosia, or my favorite, Fantail Willow, which I'm working on rooting right now and I'll blog about it later.
So, the word of the day is FASCIATION. Just like "Fascination" but without the "n".
