I am new to this site, having trouble finding what I need to know. I read you have a butterfly bush for trade. I just purchased this for my daughter and want to know how I can root a cutting from this bush. I read several articles. Since you also live in Florida I figured you would be more of an expert. I live in Palm Bay. Should I root via water or soil? Also how long of a cutting and are there any markings on the stems where it is best to cut?
