Black Jack

[Tony Avent]

Barry:

Thanks for the report from Zone 6!  The only other report that we have
so far was from southern Minnesota, where it did not survive -18F.  It
is clearly not as hardy as some more nothern ecotypes, and we prefer to
err on the side of caution.  We welcome reports from others who have
tried it outdoors.
