Purple Dragon Dead Nettle (Purple Dragon Spotted Dead Nettle) care

Light

Purple Dragon Dead Nettle wants the spot a few feet back from a sunny window — bright enough to read a paperback at noon, but the sun never falls directly on the leaves. Part shade to full shade preferred. The near-silver foliage can tolerate more sun than fully silver types but still risks scorch in hot afternoon sun. Dappled light under deciduous trees is ideal. A faint hand shadow at midday is the right amount; a sharp dark shadow means it's getting direct sun and probably too much.

Watering

Water purple dragon dead nettle every 7–10 days; water more frequently in hot, dry periods. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Maintain consistent soil moisture, especially during establishment and hot spells. Established plants in shade tolerate short dry periods. Avoid waterlogging in winter.

Soil and pot

Purple Dragon Dead Nettle grows best in average to humus-rich, well-drained soil. Adaptable to loam, clay-loam, or amended sandy soils. Target pH 6.0–7.0. Add compost to improve moisture retention in light soils. Drainage is essential in winter to prevent crown rot. 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

Purple Dragon Dead Nettle sits happiest at around Moderate; 40–60% RH humidity and -34°C to 32°C (-29°F to 90°F). Typical temperate outdoor humidity is ideal. In hot, humid climates plants may go summer-dormant. Ensure air can circulate around the mat to reduce powdery mildew risk. 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 purple dragon dead nettle sparingly. A single application of balanced slow-release fertiliser in spring is sufficient. An early-summer top-dress can extend flowering. Cease feeding by late summer to avoid vulnerable new growth before frost. 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 purple dragon dead nettle in the Growli community. Each is annotated with the most common cause so you know where to start.

• Summer heat dormancy — In zones 7–8, plants can brown and die back mid-season in high heat. Shear back to 5 cm after the main flower flush and water well; vigorous regrowth typically appears in early autumn.
• Powdery mildew — Common in densely planted areas with poor air circulation, especially when soil dries at the roots. Thin clumps and maintain even soil moisture. Remove and dispose of affected leaves.
• Rapid spread beyond intended area — 'Purple Dragon' is a fast grower and can colonise adjacent areas. Edge plantings annually and lift excess growth each spring to maintain boundaries.

Propagation

Division in spring or autumn is the easiest method. Stem cuttings taken after flowering root readily in moist, perlite-rich compost. Plants self-layer at nodes where stems touch the soil surface. 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

Purple Dragon Dead Nettle is pet-safe. Lamium maculatum is not listed as toxic to cats or dogs by the ASPCA. No harmful toxic principles are known in the Lamium genus. Considered safe in gardens with pets. 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.
