This plant came into my yard on a young rhododendron plant sold by the rhododendron society at a local Arboretum sale. It has gradually spread to cover a huge area, and birds have now moved it to a couple of other places where I am just barely able to control it. Rhizomes are very deep, so pulling them up doesn't help. I have looked on many plant sites over the years, and can't find it as a plant or an invasive.

Looks like some kind of Arisaema or other aroid. That thing on top of the scape is the 'flower'.
Send me some! Drooling

I got a laugh out of 'a plant or an invasive' -- but what a pretty little groundcover. Do you not like it? I'm always happy to have volunteers in my gardens. You may be able to ID it from your local native plant website, which often include non-native invasives.

I don't think you would really want any of this one! I have lots of Arisaema of different kinds, mainly wild, and although the scape of this plant does resemble the nice ones, the leaf is quite different. I agree, it is undoubtedly a relative of the desirable ones, but this one is taking over one azalea bed, and threatening a tree peony. If allowed to grow, the leaves get to about a foot tall, and seem to go mainly by rhizomes. I saw one place in our town where an entire bed about 15 feet in diameter had been overrun with that plant, and it did not look pretty!

Confused I guess. What exactly are the "nice ones" or "desirable ones" - and how would these "threaten a tree peony" (?) I am in a totally different eco-zone, so perhaps have no idea of how this plant may (or may not) affect a garden. From the photo provided, I thought it was lovely.

They may be growing at the Arboretum, or grown by one of the rhodo poeple who provided the rhodo..maybe pursue with one of them

I was half-kidding. Would not want to impose but I would like to have it. I have 8 acres. I could find a happy place for it. nodding

GardenerSmith, if you don't like it, get rid of it. That's the nice thing about your own yard - its your own yard. Maybe quercusnut will come over and help you dig it out. Smiling
