Thank you for your submission: It appears from your description the plant you are referring to is a common ornamental plant called Italian Arum, Arum italicum. This plant can be somewhat invasive in some situations and it is difficult to control. If you are digging the plant out be careful of how you dispose of the plant so it is not spread to other areas.
