Invasive plant

Asked April 12, 2017, 7:28 AM EDT

What is this plant that is taking over my shady garden? How do I eliminate it, as well as wild garlic/onion and lyre leaf sage which is suddenly everywhere?

That plant is Lesser Celandine a.k.a. Fig Buttercup.
It is a serious invasive threat to our native ephemeral spring bloomers, as it spreads quickly and smothers the forest floor. (A walk along some of our state parks near the river show how bad it can be.
It should be controlled. Here is our page about it: http://extension.umd.edu/hgic/lesser-celandine It should be done soon as this plant disappears by about June.

Here is our page on wild garlic/onions: http://extension.umd.edu/hgic/wild-garlicwild-onions

Lyre-leaf sage is a native, and it generally is not problematic, but you can remove or reduce it's spread if need be.
