Dear Jane and Arnold; I have always assumed that this species was too tender for my climate. Jane is a milder climate, and Arnold's is indoors. Will it stand a Zone 5 winter. We had a mild -5F this year. If I can actually grow this, I know I NEED it. Thanks Jim W. -- Dr. James W. Waddick 8871 NW Brostrom Rd.
