What is the best way to propose that an article be updated? A random undated article about butterfly bush popped up on my home page today. While I love the looks of this plant, it has seriously escaped cultivation in many areas which I think should be included as useful information to the article. Should one click on the edit button below the article itself, or somehow alert Dave/Trish, or perhaps one of the admins? This plant has become a very large problem in the Pacific Northwest, often invading logged areas and out-competing local natives. I don't have all the details, or know which other areas might also be negatively impacted, but I would think a warning of where it has made it to the 'invasive noxious weed list' would be helpful, along with the encouragement to purchase sterile cultivars which are becoming more widespread (and are equally charming).
Edited to 'call'
@Dave and
@Trish for clarification.
