Lungworts, Pulmonaria, are low-growing, spring-flowering herbaceous plants that thrive in shade. Now is a great time to divide them to make more plants for free – and Carol Klein is here to show you how it’s done. | BBC Gardeners' World Magazine

Pulmonaria is a must have in the shade garden. It’s evergreen in my zone, has gorgeous foliage and beautiful blue spring blooms. It absolutely lights up a shady space. One note about dividing: plants under patent (you know, the coolest newest varieties); dividing those and reselling is a big giant no no. One last note about dividing: treat both “halves” of your new plant like you would a new baby plant— which means watering daily for a few days; then every other day; every three days; etc. Happy
