There are hundreds of these sprouting in our new backyard (Portland, Oregon--zone 8b, mostly shaded yard below large walnut/butternut tree). They started showing up about a week ago. Any ideas would be appreciated.

Looks like a type of arum. Arum italicum maybe 🤔

Yikes. Seems like a match. https://www.oregonlive.com/hg/2014/11/invasive_italian_arum_portland.html

Any suggestions on how to mitigate? We are redoing the entire backyard, already created several berms now filled with natives, but wondering if we just sheet mulch all the areas with the arum.

How fun and beautiful your backyard is going to be! Cool link too! Is the area where they are growing contained? If so, then it’s really up to you if you like the plant or not and want to cover them up. I personally think it’s a stunning plant.

Unfortunately, it's not a contained area. It's really mind blowing how many shoots are popping up all over our backyard. I'm worried it will just take over anything else we plant/have planted. Also worried that it's poisonous because we have a couple dogs.
