A couple of weeks ago I was at Lowe's and saw this plant that I really liked and didn't know much about it, so I bought it and brought it home. Then I noticed this white stick coming out of the center and it looked nice to me (sorry don't know what is called). Yesterday this white stick started to turn yellow and I was wondering if it was something that I did wrong. This morning when I woke up the stick was almost covered by, I believe is a leaf. Does anybody knows the story behind this?
