I have my Herbaceous II class tomorrow night, I think my instructor has grown every plant known to man...I will see what she knows...

Thanks Helen, I appreciate it. It's so much fun to go to those classes at this time of year.

Well, my instructor had not grown that particular cultivar of prunella, and had only grown one other, she said that the habit was ground cover like, it sprawled about with the flowers floating above, it was pretty good the first and second years but did not return the third. So I guess that does not help too much unless that is common for that species around here...Good luck with your info quest...

Helen, thanks for checking, I appreciate it. Guess I'll keep searching for info.
