My Grecian Pattern Plant has started sprouting up everywhere. Can someone tell me the best way to terminate the plant and keep it from sprouting up everywhere? Thanks!
Acanthus mollis is it's botanical name, and it is classified as a weed.
To get rid of this plant, you have to dig up the entire area it's growing in, down about 1-1.5 feet, and either just toss out the soil, or carefully sift through it, removing all the tubers and plant bits.
If you miss just one bit of root, it'll be back soon. Round up is a waste of time.
