Iris are tough. Iris can be cut down to the earth, grow back, cut down again, grow back, be cut down AGAIN so that not a green fragement is seen, and grow back. (Ask me how I know.)
But day lilies… day lilies can be divided using a spade, tossed into holes with no prep, covered over, and spring to life next year. They can be tossed on top of a groundhog hole to block it, have no additional soil, and continue to grow and bloom (also: may not have been a groundhog hole after all). Day lilies can only be routed by digging and digging and digging… and at some point you just throw up your hands and decide, y’know what, they look okay, all things considered.
Great looking irises, btw, Dusty. Looking forward to seeing the full blooms.
