question about Nest Egg Gourd

Have you grown these? http://www.gardenguides.com/seedcatalog/vegetables/gourdnestegg.htm

I am growing these from seeds and they are ready to be put in a container. How large a container will I need? Do they sprawl or vine ? ( I started the seeds late but figured that I'll just see how far along I can grow them in my area. )

http://davesgarden.com/pf/go/54374/index.html. It is a vining cultivar, but folks do grow them in pots. I would think about 5 gallons would be sufficient.

Thank you, Farmerdill. I wanted to try them out this year and see how they do in pots. If they turn out cute, I may also be able to grow them again during winter in a greenhouse, as one person in the PF suggested, and have them in time for Easter.
