Marybeth, from the photo, I'd have to agree with you. Doesn't red hot poker have tube-like flowers? Those look like round balls to me. I've seen it, I just have never known what it was called.
IF I am correct those berrylike balls will turn a gorgeous red later on. The berries are very poisonous so beware!! YES it is an Arum plant, MaryBeth is right. When I do my mail route I pass a house that has a few as well. Adorable but as I said, the berries are poisonous
Wow - we had one pop up (we've lived here 18 years and it was the first time we'd ever seen it). The oddest thing about it is that it doesn't have foilage. Thanks for ID-ing it.
