Care at a glance

Light

The Goldilocks zone. Not the south-facing windowsill (too hot, too direct), not the back of the room (too dim, growth stalls). Best in partial shade to filtered light. The silver coloration intensifies with some morning sun but strong afternoon sun bleaches and scorches leaves. Dappled woodland conditions are ideal. If you can't decide, a free phone lux-meter app aimed at the leaf at noon should read between 800 and 1,500 lux.

Watering

Watering heuchera 'silver scrolls': when the top 2-3 cm of soil is dry, roughly every 7-10 days. 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. Needs consistently moist but well-drained soil. Avoid waterlogging around the crown. During dry spells, increase frequency; reduce in winter when growth slows.

Soil and pot

Heuchera 'Silver Scrolls' grows best in rich, well-draining loam or humus-amended soil. Thrives in fertile, moisture-retentive yet free-draining soil. Work in plenty of organic matter before planting. pH 6.0–7.0 is preferred. 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

Heuchera 'Silver Scrolls' sits happiest at around 40-60% humidity and 5-25°C (41-77°F). Tolerates typical garden humidity levels. Ensure good air movement around plants to reduce risk of fungal leaf spots, particularly in humid summers. If you keep the room above 5 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 heuchera 'silver scrolls' sparingly. Feed with a balanced granular fertiliser at the start of the growing season. Liquid feeds at half strength every 4-6 weeks through summer maintain vibrant foliage colour without encouraging excess soft growth. 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 heuchera 'silver scrolls' in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Crown rotPoor drainage causes crown softening and collapse; improve soil drainage and avoid overhead watering.
  • Vine weevil larvaeRoot-feeding grubs cause sudden wilting; apply biological nematodes in late summer or early autumn.
  • RustOrange pustules on leaf undersides in cool, wet conditions; remove affected leaves and apply a suitable fungicide.
  • Leaf scorchPale, bleached patches result from excessive sun exposure; relocate to shadier spot.
  • Slugs and snailsYoung foliage is susceptible in spring; use copper tape, grit mulch, or organic slug pellets.

Companion plants

Heuchera 'Silver Scrolls' pairs well with Hosta, Tiarella, Astilbe, and Bleeding Heart. These are species with similar light and water needs, so you can group them in the same room or on the same shelf and water as a batch.

Propagation

Divide clumps every 3-4 years in spring or autumn. Each division should include a section of crown with attached roots. Cuttings of side shoots can also be rooted in a gritty compost mix. 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

Heuchera 'Silver Scrolls' is mildly toxic to pets. Not individually listed by the ASPCA. Heuchera as a genus is considered mildly irritating if consumed; exercise caution with pets and small children. 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.
