Planting Instructions for Pulmonaria (lungwort):

Bloom Time:  Spring Light:  Part shade to full shade
Soil:  Humus-rich, well-draining, woodland-like soil Moisture:  Average to moist
Planting Depth:  1" deep, mulch 1 to 2" Spacing: 15 to 18" or more, depending on variety

Upon arrival:  Unpack box and check that you have everything on your packing list. Pulmonaria likes to stay a little on the dry side when bare root. If the bag has a lot of condensation you can open it and let it air out for a little while then try to plant within a day or two of arrival.

Soil/Location:  Plant your Pulmonaria in part shade to full shade in humus-rich, moist but well-drained, woodland type soil. Add compost or peat humus to enrich and loosen the soil if needed and remember to keep the soil light and airy for perennials, so cover them with loose soil and don't pack them in after planting.

Moisture:  Pulmonaria is fairly drought tolerant but does enjoy some regular watering and should be watered deeply if they wilt. Burying the crowns completely and mulching lightly helps keep them cool and moist.

Spacing:  15 to 18" or more, depending on variety

Depth:  Plant with the top of the crown about 1" below soil level and then mulch them after planting. This keeps them cool and moist in the summer and protects them from drying winds in the winter. It is best to bury some of the stems as new roots only form from the base of the foliage/top of the crowns. If the crowns ever become exposed you should lift and replant deeper or topdress with a layer of compost and mulch, otherwise they will dry out and perish.

General Instructions:  Enrich your garden with compost or peat humus and mix a couple teaspoons of garden food or bone meal into the planting hole. Plant the roots at the depth listed, making sure no crown or roots are showing, then water in well. Your plants should emerge soon but shouldn't need any extra water until they've completely sprouted. Then they don't mind being watered a few times a week and should be watered deeply if they wilt.

Landscape Uses:  Pulmonaria make excellent border or accent plants in the woodland garden and look great in mass plantings. Combine them with hostas, ferns, foamflowers (Tiarella), bleeding hearts, and shade loving ornamental grasses such as Hakone grass and carex.

Pulmonaria will self-sow freely but the seedlings are easy to spot and easy to transplant if needed. The new seedlings will have highly variable foliage and flowers so are fun to grow since you never know quite what you will get.

Powdery mildew can be a problem on some varieties. This tends to occurs after the plants are finished blooming and if so you can just cut them down to the ground and the mildewed leaves will be replaced by new clean leaves. Or if you prefer a preventive fungicide spray just as they finish blooming can help to keep them clean looking.
