Aegopodium podograria #1 by J.G. in S.F.
TheGardenLady received this question from Janet.
I was given some hostas and there were some pieces of Snow on the Mountain mingled with them, which is taking over everything. How can I kill the snow without killing the rest of my plants? I have dug until I’m blue in the face.
There are quite a number of plants that were brought to this country because they looked pretty and horticulturists or gardeners wanted to plant them in their gardens in America or wherever they moved; then these plants became invasive. Unfortunately Snow on the Mountain, ‘Aegopodium podagraria Variegatum’, also known as Bishop Weed or Goutweed is one of them.
One nursery touts it as the number one seller for a ground cover. So it is still being sold. It is advertised to use for difficult sites. Many people say they love the plant and it isn’t invasive for them. However, some people rue the day that this plant entered their yard. One lady said when she sold her house she didn’t tell the new owners all they were getting. The government lists this plant as an AGGRESSIVE invasive (see here).
People who buy plants should check the invasive plant list before buying plants or buyer beware. Even nurseries don’t seem to keep on top of the invasive plant list, so they might not be aware of the problem. Always check pots when buying plants to be sure that you are not getting an unwanted guest, whether weed, disease or pest. But you seemed to have the misfortune of inheriting it when you got your hosta plants from a friend.
