Both the Plants Database for this organization and the PlantFinder database for the Missouri Botanical Garden in Saint Louis list the hardiness range for Chinese Rice Paper Plant as 8A and 8 respectively.
I just want to bring to your attention the fact that I have been successfully growing this plant in zone 7A for the past nineteen years. It decidedly dies to the ground each winter, but it reliably returns each spring. The maximum height it has achieved in zone 7A has been, to the best of my knowledge, between six and seven feet. In all these years I have yet to see it flower. But it makes an impressive and highly attractive foliage plant. In addition to the gardens I have grown it in... it has also been successfully grown in the AABGA garden that comprises part of our municipal zoo.
