It's an evergreen (wintergreen) in zones 9 and above. Dense spreading plant.
Herbaceous perenial in zones 8-5.
Here is a detailed description on how overwinter it outdoors: http://www.ebay.com/gds/How-to-mulch-a-Musa-Basjoo-for-a-Zone-5-Winter-easily-/10000000007789832/g.html?rmvSB=true
I grow it outdoors since 2012. I mulch it with leaves 1-1,5ft high and spread it 6ft (2m) wide. Then cover with plastic 6ft x 6ft (2m x 2m) and tie it down with bricks, so the wind doesn't blow the plastic away.
This is the most cold hardy banana. Roots are more cold hardy than the leaves. In USDA Zones 5-8, plant will die to the ground at 32 degrees F (0 C). Cut back the trunk to 1-2' (30-60cm). Leave in the ground. Wrap up the stems with bubble wrap or plastic and place a thick layer of mulch on top to protect the roots. Keep them dry in winter.
Likes neutral pH soil with good drainage. Water regularly throughout the growing season. Cold hardy down to USDA Zone 4a. Growing range - Zone: 5b-10b; 12 - 15 ft. (3.6-4.7 m) high
It doesn't like standing water, but needs moist soil all the time. Apply fertiliser to encourage growth.
You are getting 20 cm high plant (9 cm pot for European deliveries, no pot and wrapped up in plastic for international deliveries).
