Colour of Stonecrop?

[Eorl of Rohan]

In LOTR, it is said that stonecrop growing among the fissures of the hair of the statue of the king looked like a crown. "Look! The king has got a crown again!"

I read somewhere in barrowdowns, written by the great barrow-wigth himself, that stonecrop was red, not yellow. Surprised, I check my copy of LOTR and it still said "yellow" if I was not blind.

Putting the matter of yellow or red-haired king to one side, what color is the stonecrop?

[Sharkû]

You're right, it says they're yellow in the book.

[The Barrow-Wight]

I said that? I don't think so.

Until reading this topic, I don't ever recall using the word 'stonecrop' in anything that I have ever written. In fact, I didn't even know what stonecrop was until I just now went and looked it up.
