Ian, There was a discussion about cold hardy LA's last year (on
Sept 19 under Ginny Prinz). Later in the fall I got 2 Dorothea K
Williamson's which are supposed to be very aggressive and hardy. At
least one of them is going to bloom this summer along with the
JI's.  I got Black Gamecock this spring so I won't know until next
summer how it does here.
