For those of you who've had the herbaceous growth come up from your nurse root, did all of those come from nurseries or big box stores? I remember Nate from Solaris talking about the care they take in using roots known not to be adventitious for grafting—has anyone ever had one from the big US growers sprout herbaceous? I've actually never had one of the imported ones from the big box stores even survive a CO winter so I have nothing to compare it to but I've never had a herbaceous sprout from Solaris, Adelmans, Song Sparrow, A&D or Cricket Hill.
