I am so glad that a friend directed me to your site. My wife and i have been driven crazy battling this pernicious invader. We are in the Baltimore area, and until just now, nobody has been able to identify this pest for us. All our control efforts have failed.

We got some plants from a public garden in Baltimore some years ago and thought that the pinellia must have arrived with them. However people who work there said they were unaware of this weed, which surprised us greatly.

But now another possibility presents itself. Our son was a student at Swarthmore College some years ago–so maybe it hitchhiked on his shoes or something (he was not a gardener then!).

Pinellia is one of the most pernicious weeds in the gardens at Swarthmore. We have eliminated it from some garden areas, but only by digging out the soil, sifting it through a screen and picking out all the parts of the Pinellia.

I have been fighting this monster weed for over 15 yrs. Don’t know from whence it came, but i may be responding to Trichlopyr (Ortho). We have not been able to correctly identify it until today from the wonderful Atlantic Co. Extension agent. Digging it out – corm and all, is not enough. It keeps spreading by the corm and gazillion rhizomes. extending from the corms (or nuts).

When we first saw Pinellia ternata, it was growing in a newly built raised bed that had been filled with fresh soil . I am glad that I saw a picture of it in an id of invasive plants book that I had purchased recently. I wrongly thought that it was some kind of Jack- in- the -Pulpit and was going to plant them in my garden at home. I would seriously look out for these “cute ” little pulpit look-alikes in soil brought in when preparing a new garden site or raised beds! This is what seems to have happened to us , as I certainly hadn’t seen hide nor hair of them prior to the raised beds being built and filled with soil.

Pinellia ternata was widely sold 10 or 12 years ago in Southeastern PA as the only Pinellia that wasn’t invasive. In it’s EARLY years in our garden it was a delightful plant but in 6 or 7 years it gets entrenched and the plants begin to appear further and further from the parent clump. I agree it should only be grown by those who understand it’s true nature. It could easily become problematic. Last year I saw a new variegated form that was very tempting and I’m sure many have a tiger by the tail.
