Lungwort Blue Ensign

The 'Blue Ensign' lungwort (Pulmonaria) is a very healthy and hardy perennial that usually does not suffer from diseases or pests. It is a vigorous plant. Slugs can occasionally appear on lungworts, but this cultivar is less attractive to them due to its coarser leaves.

The 'Blue Ensign' cultivar will delight you with its flowers very early in spring, usually from March to May. Its flowers have a magnificent royal blue color. A unique feature of this cultivar is that the flower color is very intense, and unlike many other lungworts, it does not change to pink or purple after opening, but remains pure blue.

No, and that is a great advantage for lovers of elegance. 'Blue Ensign' has solid dark green leaves without spots. This gives the plant a very calm and unified appearance, which perfectly allows those bright blue flowers to stand out.

Yes, Lungwort is an edible plant. The young spring leaves can be added to spring salads, soups, or stuffings, much like spinach. In folk medicine, the plant was historically used for its effects on the respiratory tract, which is also where its name comes from.

No, Lungwort is not poisonous. It is safe to grow in gardens where children or pets (dogs, cats) are present. On the contrary, it is a useful and safe plant.

Yes, absolutely no problem. Lungwort 'Blue Ensign' is fully frost-hardy down to -30 °C (zone 4a). It does not require any special winter protection. Although the above-ground part dies back for the winter (it is not evergreen), the root system survives safely in the ground, and the plant will beautifully sprout again in the spring.

Yes, container cultivation is possible if you meet its requirements for shade and moisture. The pot should be sufficiently large and have drainage holes. Soil in a container dries out faster, so you will need to water more frequently. For the winter, it is advisable to sink the pot into the ground or wrap it with insulation, as roots in a container freeze more easily than those in open ground.

In a shaded flower bed, it looks amazing in combination with spring bulbs (snowdrops, snowflakes) that bloom at the same time. Great neighbors also include hellebores or ferns. The dark green leaves of 'Blue Ensign' form a calm background for more colorful shade-loving perennials.

This perennial prefers consistently moist soil. It is not a drought-tolerant plant, nor does it like to be waterlogged. Especially in the first year after planting, ensure regular watering so the seedlings establish their roots well. If you plant it under trees, keep in mind that trees can draw a lot of water from the soil, so on hot summer days, the lungwort (Pulmonaria) may require supplemental watering.

The recommended planting spacing is 30–40 cm. If you want to achieve faster coverage and create a continuous carpet, count on approximately 7 to 9 plants per square meter. The plants will spread out in width over time.

Regular pruning is not necessary, but the plant benefits from clearing away old and dry leaves early in the spring. After flowering, you can also remove the spent flower stems, which encourages the growth of new, healthy leaves that will decorate the flower bed until winter.

Lungwort is not demanding in terms of nutrients. It is perfectly sufficient to add a layer of compost around the plant in the spring. This will provide nutrients and help retain moisture in the soil. If your soil is very poor, you can use a standard organic fertilizer for perennials.

Not at all. Lungwort 'Blue Ensign' is an undemanding perennial suitable even for complete beginners. If you choose the right shaded spot and ensure it does not dry out completely, it will grow almost on its own. It is a long-lived plant that will thrive in the same spot for many years without complicated care.

It thrives best in humus-rich, loamy soil. The soil should be nutritious and capable of retaining moisture, while remaining sufficiently permeable. Before planting, we recommend incorporating compost or leaf mold into the soil, which helps mimic the natural environment of the alluvial forests where lungworts originate.

Lungwort is an ideal plant for partial shade to shade. It is perfectly suited as underplanting beneath mature trees or shrubs, which provide the necessary protection from direct midday sun. It will also thrive on the north side of a house or in shaded corners of the garden where other flowering perennials might struggle. Direct sun could scorch its leaves.

The simplest and most reliable method is division of clumps. You can do this after flowering or in the autumn. Carefully dig up the plant and use a spade or knife to divide it into smaller sections, which you then replant. Lungwort also self-seeds, but with cultivars, the seedlings may not have the same characteristics (e.g., flower color) as the parent plant.
