|If I cut this plant back,will it grow back with it|
I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
I am not familiar with a plant called "sister plant". Can you provide another name or if possible its latin name. Even with other common names or a very detailed description we can probably figure out what plant you are referring to.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
