Fasciation

An amazing example! I knew nothing about this until I posted the picture below, a while back, of Spear Thistle in this case...

Cacti

You can buy cacti that suffer from this, though normal ones seem much preferable.

In that year I found white

In that year I found white clover and Dandelion flowers all suffering from it, I wondered if it was something airborne that had caused it. I still look in the area of the Marsh Thistle but have never found anymore.

Fascinating (Sorry)

I was very interested in your observation above. It has solved a mystery for my wife and I.
We found a similarly affected Spear Thistle, which I posted on i-Spot on 28.5.11.
We did not have an id of what it could have been and our local Natural History Societies could not help.
Thanks for your help.

Happens occasionally in a wide range of plants

caused by various interruptions to cell division.Likely to be more visible in non woody plants?A magnificent specimen.
