I am adding a picture to show you what I found. I found this in 2 places. The stem is so brittle, I was able to to this with my finger nail. I will be trimming it after I post this picture. I'm sure more of the stems are probably like this. I should have covered it, but here in San Antonio, it rarely gets under 40 degrees here in the winter. Not sure if I should dig it up or leave it for a couple more months, but I see no green growth at this time. Thanks for looking and any comments are appreciated.
