Perennials can be the backbone of anyone’s garden – they certainly are for mine. I choose perennials that bloom in succession, support native insect populations, are pretty, and attract lots of butterflies! Despite living in Zone 5 in Northeast Kansas, where the weather is constantly changing, I have a very diverse garden.
