did it previously have yellow grooves or were you told it was yellow groove - i ask because i have heard of 2 recent incidents whrein an ohio supplier has freely substituted bissetii for yellow groove and vice versa

I had a yellow groove that became all green after dieing to the ground at -24*F. It did have a yellow groove before that and it has not come back in two years.

sounds like the same thing bill. mine had the yellow and lost it.

do you think it may come back at some point.
