    I am considering adding Kerria japonica 'Pleniflora' to my garden but wonder whether it becomes invasive in northern Virginia. Does anyone know?

    I live in the mountains of North Carolina and I have had one for about 15 years. It is moderately invasive here but easily controlled.

    My Kerria Japonica has done well for 10 years or so. Summer of 2014 we lost half the plant, which we put down to the severe winter. We pruned (maybe not enough), and now this year it had very few flowers and the leaves are mottled and spotty. Can it be saved by cutting it way back?
