Small Celandine Ranunculus Ficaria
I know this plant is invasive, but it is not illegal to plant it in NYS. It is such a beautiful ground cover. I would like to plant it under my peonies to keep weeds down. Would it be harmful to the peonies?

I don't necessarily think it will threaten your peony but without suitable measures taken, this plant could get out of control. I would ensure that it stayed within its bounds by implementing some type of edging and installing it a few inches in the ground. You could also place landscaping fabric or newspaper down around your peony plants and add mulch to keep the weeds down and then simply place containers of the celandine around it for looks.
