    Yes. Buttercups are like crabgrass - you just have to keep digging & pulling, and leave them no place to grow, or learn to live with them.

    Re: Buttercup Woes!!!

    Considering location you are probably talking about quackgrass.

    What is that? I never heard of it. We have several different species [so I assume, as they are very different] of invasive grasses, but nobody calls them that. As you can tell, I don't know many botanical names.

    Crabgrass (Digitaria sanguinalis) is a summer annual and not usually a big problem in our cool climate. I have seen it here perhaps several times at most. Quackgrass (Elymus repens) is the persistent creeping tough-rooted perennial that "many Seattleites call crabgrass" (Jacobson, Wild Plants of Greater Seattle - Second Edition).

    Actually, Elymus repens - now correctly Elytrigia repens - is Common Couch. Seems to be another case of Seattleites misnaming imported grasses, that Jacobson might want to add a note of.

    He lists the plant as Elymus (Agropyron, Elytrigia) repens Quackgrass. Couchgrass. Quitchgrass. Dog Grass. Twitch. Devil's Grass. Whickens. Scutch Grass. Witch Grass. Quickgrass.

    because THAT is the world that exists, a world of evolving botanical names subject to acceptance and rejection by various authors - and a world of many, many more non-botanists than botanists who often use multiple common names for the same plant. Individuals can claim that there is only one "correct" common name and one botanical name in use for a plant a thousand times and it will not change the essential actual fact that this is not the case (except where it happened to be that only one common name and one botanical name where being used for a particular plant).

    I didn't bother to get the identity of the thugs who attacked my borders - I simply pulled them up & burned them.
