THe Camas lillies are indigenous to this area and have bulbs deep under ground. The multiply and have spread from the neighbors yard. They are too much work to pull up old leaves, and I can't even find the bulbs.
Suggested Project Book
Canna lilies sometimes require chopping off the bulbs and roots. If you don't want to dig them out, you may have to apply Brush killer or Round Up. Read carefully before you apply either, then install barrier plants.
to kill the lilies you can use roundup or a brush killer spray you may have to apply it a couple times but it will kill the lillies coming into your yard
