Lynn,
They had such great names Heuf #1, Heuf #2 and 'Palaisii'. Helen named the first two as 'Apache' and 'Belcor'. 'Palaisii' was really 'Correvon's Form' but that was the name Bill Newhard had received the plant and all we knew that it was way different than the other two. 'Correvon's Form' is the parent of many of Bill Nixon's and Ed Skrocki's cultivars. The English had a couple more that we didn't have and those made it to the US in the 70's and 80's. When we did the Dalton project we then were able to identify 'Palaisii' as 'Correvon's Form'. There were no clones from England that matched #1 or #2 so that is when Helen did the renaming,
Sandy MacPherson had received both of these clones from Sanford but we don't know any pre-history from Sanford.
Hope that helps!
Kevin
