Raspberry Splash Pulmonaria (Raspberry Splash lungwort) care

Light

If you have a corner where every other plant turned leggy and died, try raspberry splash pulmonaria. Full to part shade gives the best foliage and flower colour. Strong sun, especially over dry soil, scorches the leaves; this cultivar tolerates fairly deep shade well. The catch: when a low-light plant does fail, it's almost always because someone watered it on the same schedule as their brighter plants. Less light = less water, every time.

Watering

Watering raspberry splash pulmonaria: keep soil evenly moist; water every 4-6 days in dry conditions, more in pots. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Dislikes drying out, which leads to wilting and mildew. A leaf-mould mulch helps retain moisture. Settled clumps in cool shade weather short dry periods without lasting harm.

Soil and pot

Raspberry Splash Pulmonaria grows best in moist, humus-rich, well-drained loam. Prefers fertile, organic-rich woodland soil that holds moisture yet drains freely. Neutral to slightly alkaline pH is ideal. Improve with compost or leaf mould; avoid hot, dry, sunny spots. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Raspberry Splash Pulmonaria sits happiest at around Ambient outdoor humidity humidity and -28 to 24°C (-18 to 75°F). A hardy outdoor perennial needing no special humidity; it favours the naturally cool, moist conditions of shaded borders. If you keep the room above year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed raspberry splash pulmonaria sparingly. Undemanding; an annual spring mulch of compost or leaf mould typically meets its needs. A light balanced feed in spring on poor soils boosts the foliage. Avoid excess nitrogen, which softens growth and encourages mildew. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on raspberry splash pulmonaria in the Growli community. Each is annotated with the most common cause so you know where to start.

• Powdery mildew — Common in dry shade, particularly after flowering. Keep soil moist, shear back affected foliage to regrow, and improve air circulation.
• Leaf scorch or fading spots — Caused by too much sun or dry roots. Relocate to cooler, deeper shade and maintain consistent soil moisture with mulch.
• Tired foliage after bloom — Leaves can look worn once flowering ends. Cut the clump back hard to trigger a fresh, well-marked flush.
• Slug and snail damage — Soft new growth is grazed in damp shade. Use barriers or wildlife-safe slug controls around emerging spring crowns.

Propagation

Divide clumps after flowering or in autumn, replanting healthy sections in moist, enriched soil. This sterile-leaning named hybrid is propagated by division to remain true to type; seed is unreliable. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Raspberry Splash Pulmonaria is mildly toxic to pets. Not individually listed by the ASPCA, so its pet status is unconfirmed; Pulmonaria contains pyrrolizidine alkaloids and saponins (classes the ASPCA flags as toxic) and bristly trichomes may irritate skin. Treat with caution and verify with a vet — do not assume pet-safe. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
