Musa basjoo stumps in December

The Musa basjoo banana tree mentioned in the October post has been cut down for the winter.  Here is a view of the interesting patterns of the cross-section of the stems. The air temperature has been below freezing for a couple days and some snow remains on the ground.  I was interested in finding this stump to see if there was any sap getting exuded from the roots and then freezing but the ice on the stump could be from the fallen snow too.

Pictures taken December 1, 2011 at Purdue Horticulture Gardens.
