Pulmonaria 'British Sterling'

Lungwort (Pulmonaria 'British Sterling') is an easy-to-care-for evergreen perennial. It has a stunning foliage of grey-green leaves, adorned with silver spots and a profusion of powder blue, tubular flowers in the spring. When conditions are favourable, these can re-bloom through to autumn. Its genus name comes from an old belief that its spotted leaves were based on representations of diseased lungs, though of course this has since been proven false. This durable plant is sun and shade tolerant and prefers well-drained,neutral to acid soils. Its ideal for adding some summer color to partly shaded spots in the garden.

watering

Lungwort (Pulmonaria 'British Sterling') requires moist soil, and the frequency of watering should depend on the growing season and temperature. It is best to water about once a week in the spring and summer when temperatures are warmer. During periods of rain, less frequent watering may be necessary. In the fall and winter, when temperatures are cooler, watering should be reduced to about once every 2 weeks. When watering, be sure to water deeply and evenly. Allow the soil to dry between waterings, and be sure to check the soil’s moisture level before watering.

sunlight

Lungwort (Pulmonaria 'British Sterling') is a shade-loving evergreen that prefers filtered, morning sunlight. This plant does best when receiving 1-3 hours of bright indirect sunlight each day. If it receives too much direct sunlight, it will quickly show signs of wilting. It is important to avoid direct afternoon sunlight, as this can cause the plant to become scorched. Additionally, an overexposure to too much sun can cause the colors of the plant’s foliage to fade. For optimal growth, plant your lungwort in part shade to full shade in order to ensure that it receives the necessary amount of sunlight.

pruning

Lungwort (Pulmonaria 'British Sterling') should be pruned in early spring, when new growth begins to appear. Pruning should only be done to remove old, dead leaves and stems, as this will help encourage new growth. Prune lightly, as this plant is prone to becoming leggy if pruned too heavily. Also, avoid pruning the flowers off the stems, as this will reduce the flowering in the subsequent year.
