I've had my dnp all summer and it's struggled but lived. It shot out several leaves, some with black spots, but never grew very tall. Now that its winter I brought it in and it looks like it's gonna croak! What's up with em?!! They must be genetically weak or somethin'. I've heard about a lot of people loosing them and I think I do pretty good with nanas but this damn thing, I don't know.
