Pulmonaria 'Raspberry Splash' (PBR)

Water

For Lungwort 'Raspberry Splash,' it's important to keep the soil evenly moist, especially during the growing season in spring and early summer. Watering should be done deeply once the top inch of soil feels dry, which may be approximately once a week, though this frequency can vary based on climate and weather conditions. The goal is to provide the plant with roughly 1 gallon of water every week, but this should be adjusted to ensure the soil doesn't become waterlogged or overly dry. During hot, dry spells, additional watering may be necessary, and during the winter months, watering should be reduced as the plant's growth slows down.

Light

Lungwort 'Raspberry Splash' thrives in partial shade, as this mimics its natural woodland habitat. The best location would offer some morning sun followed by afternoon shade, or dappled sunlight throughout the day. Avoid placing it in full sun, as this can scorch the leaves, and likewise, too much deep shade can reduce flowering and cause the foliage to become less vibrant.

Temperature

Lungwort 'Raspberry Splash' prefers temperate conditions and can tolerate a range of temperatures from about 50 to 75 degrees Fahrenheit, which is commonly found in many gardening zones. It's hardy and can withstand winter temperatures down to about -20 degrees Fahrenheit but should be protected from extreme frost. The ideal temperature range for promoting good growth and vibrant blooms is between 60 to 70 degrees Fahrenheit.

Pruning

Pruning Lungwort 'Raspberry Splash' helps to maintain its shape and encourages healthy growth. After the plant flowers in the spring, deadhead the spent blooms to promote a second, albeit smaller, flush of flowers. Prune back any damaged or dead foliage in early spring or immediately after flowering to keep the plant looking tidy and to encourage air circulation. Pruning is typically needed once a year; however, occasional removal of damaged leaves throughout the growing season is beneficial.

Cleaning

As needed

Soil

Lungwort 'Raspberry Splash' thrives best in a soil mix that is well-drained yet retains moisture, rich in organic matter with a pH ranging from 6.0 to 7.0. A blend of loamy garden soil, compost, and a small amount of perlite or sand would create an ideal environment for this plant.

Repotting

Lungwort 'Raspberry Splash' does not need frequent repotting; it typically should be repotted every 2-3 years to refresh the soil and accommodate root growth.

Humidity & Misting

Lungwort 'Raspberry Splash' prefers moderate to high humidity levels but is quite tolerant of a range of conditions; aim for a humidity level of around 40-50%.

Suitable locations

• Indoor

  Place Lungwort 'Raspberry Splash' in bright, indirect light; keep soil moist.

• Outdoor

  Plant in partial shade, moist soil, shelter from harsh sun.

• Hardiness zone

  4-8 USDA

Life cycle

Pulmonaria 'Raspberry Splash', commonly known as lungwort, begins its life cycle as a seed, which, after a period of dormancy and once conditions are optimal, germinates and sprouts into a seedling. The seedling establishes itself and grows into a vegetative plant, producing characteristic leaves with silver spots and developing a strong root system. As the plant matures, it enters the blooming phase, typically in early spring, showcasing clusters of pink to raspberry-colored flowers that attract pollinators. After pollination, the flowers develop into fruit containing seeds, completing the reproductive cycle. The lungwort then enters a period of senescence during the hotter summer months, where it may die back partially, only to regrow from the root system as the weather cools. This perennial plant continues its cycle annually, emerging from dormancy each spring to repeat the process.

Propogation

• Propogation time

  Spring-Early Summer

• Pulmonaria 'Raspberry Splash', commonly known as Lungwort, is best propagated by division. The optimal time for dividing lungwort is in the fall after the plant has finished flowering or in the early spring just as new growth begins. To propagate by division, carefully dig up the plant, making sure to keep a good amount of soil around the roots. Gently pry or cut the plant into smaller sections, each with several shoots and a healthy supply of roots. Replant these divisions immediately into moist, well-drained soil, spacing them about 12 inches (approximately 30 centimeters) apart to allow for growth. Water the newly planted divisions thoroughly to help establish them. This method is effective because it maintains the characteristics of the parent plant and allows the gardener to quickly increase their stock of lungwort.
