Ipomoea indica help

I have seen a Ipomoea I.indica for sale at a local garden centre and wondered if anyone could help me before I buy one.Are these plants hardy enough to survive winter in a greenhouse,and also are they vigorous growers.Any help would be appreciated.
Thanks,
Stokie.

They are certainly hardy enough to survive winter in a greenhouse, and if they like the position they grow like other more common ipomoeas.They are said to be much hardier than the normal ones. This site has a picture and brief description, just put 'ipomoea indica' in the search box:
