Name: Jacquie (JB) Berger Wrightstown, New Jersey (Zone 6b)
I am in Zone 6 and I know it is not hardy here. Maid of Orleans is the least hardy of them all so I read somewhere. I think Top Tropicals recommends you live in Zone 8 or higher to grow some of the Sambacs. You may want to look them up in Top Tropicals. They have a wonderful booklet for sale on them also. It is called Jasminum Sambac Albsolute Flower. Good condensed information. Hope this helps.
