Lynn,
Bill Newhard did grow some seedlings (I grew two of his dark-leaved ones in the early 70's) but as far as I know he never really named any of his own. He did sell a lot of semps in the early 70's and it may be one that he sold and no one knew its actual source. Shirley Rempel was credited with my 'Jungle Fires' for a while too and still is in some lists. That is wrong. at first i thought she introduced it, but it appears in Helen's list first, not hers.
Bill had gotten things from Sanford directly so it might have come so named and he just perpetuated the name.
Anyway, just my two cents!
Kevin
