Please post plant questions in the Ask A Question forum. The comment section to any plant database entry is as stated, for posting "an informative comment about a plant" such as personal growing experiences and extra info about that plant that stays as a permanent comment. It does not get seen by anyone unless they happen to open the entry and scroll down.

FYI, not knowing what zone NC is but this is a perennial in the mildest of winters, from what I found, zone 8 and up.
Please let me know when you have seen this so I can delete the thread.
