Burgundy Periwinkle (Purple Periwinkle) care

Light

The Goldilocks zone. Not the south-facing windowsill (too hot, too direct), not the back of the room (too dim, growth stalls). Thrives in partial to full shade; tolerates deep shade under deciduous trees better than most groundcovers. Flowers most prolifically with 2–4 hours of dappled light. Full sun causes leaf scorch and faded flower colour, especially in hot summers. 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 burgundy periwinkle: weekly during establishment; every 2–3 weeks once established. 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. Drought-tolerant when roots are settled (after one full growing season). Water deeply but infrequently to encourage deep rooting. Avoid waterlogged soils; good drainage is essential to prevent root rot and stem blight.

Soil and pot

Burgundy Periwinkle grows best in well-draining loam or sandy loam; adaptable to clay if not waterlogged. Tolerates a wide pH range (5.5–7.5). Amend heavy clay with grit or coarse compost before planting. A 5 cm layer of organic mulch after planting retains moisture and moderates soil temperature during the establishment year. 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

Burgundy Periwinkle sits happiest at around 40–70% humidity and -20°C to 30°C (-4°F to 86°F). Adaptable to average outdoor humidity levels; not sensitive to humidity fluctuations in temperate climates. Good air circulation between stems reduces the risk of fungal leaf diseases such as Phoma or Botrytis. 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 burgundy periwinkle sparingly. Apply a balanced slow-release granular fertiliser (10-10-10) once in early spring as new growth emerges. Over-fertilising with high nitrogen promotes lush foliage at the expense of flowers and can increase susceptibility to stem blight. 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 burgundy periwinkle in the Growli community. Each is annotated with the most common cause so you know where to start.

• Stem blight (Phoma or Botrytis) — Stems blacken and collapse, often following wet, cool springs. Improve air circulation by thinning dense patches, avoid overhead irrigation, and remove infected stems. Fungicide applications (chlorothalonil or copper-based) can help in persistent cases.
• Deer and rabbit browsing — Deer will browse young growth, especially in winter when other food is scarce. Apply deer-repellent sprays seasonally or use physical barriers in high-pressure areas. Established dense mats are somewhat less palatable.
• Invasive spreading — Vinca minor is listed as invasive in parts of the eastern United States and Pacific Northwest. Stems that escape into natural areas can out-compete native vegetation. Edge plantings regularly with a spade and dispose of clippings — do not compost.

Propagation

Easiest by stem cuttings (5–8 cm tip cuttings taken in late spring or early summer, rooted in moist compost) or by division of rooted stems in spring or autumn. Self-layers freely — detach and transplant rooted runners to new areas. 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

Burgundy Periwinkle is toxic to pets. Vinca minor contains vinca alkaloids (vincamine, vinblastine-related compounds) toxic to dogs, cats, and horses. The ASPCA lists Vinca species as toxic to dogs, cats, and horses, causing vomiting, diarrhoea, low blood pressure, neurological signs, and seizures. Keep pets away from this plant. 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.
