Salvia splendens 'Sizzler Burgundy' (Sizzler Burgundy Salvia) care

Light

Salvia splendens 'Sizzler Burgundy' needs sun on the leaves, not just bright ambient room light. Best in full sun for the densest, most colourful flower spikes, though it tolerates light afternoon shade in very hot climates. Deep shade causes leggy growth and reduced flowering. A south or west-facing windowsill in the northern hemisphere is the default; anywhere else, expect the plant to stretch and pale out within a season.

Watering

Water salvia splendens 'sizzler burgundy' when the top 2-3 cm of soil is dry, roughly every 3-5 days. 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. Prefers consistently moist but well-drained soil and is less drought-tolerant than gazanias or daisies. Avoid both drying out and waterlogging. Mulching helps retain moisture in beds; containers dry faster and need closer watching.

Soil and pot

Salvia splendens 'Sizzler Burgundy' grows best in fertile, moist, well-drained loam or quality potting mix. Grows best in rich, moisture-retentive yet free-draining soil. A neutral pH around 6.0-7.0 is ideal. Improve poor soils with compost and ensure drainage; soggy ground encourages root 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

Salvia splendens 'Sizzler Burgundy' sits happiest at around 40-60% humidity and 16-30°C (61-86°F). Tolerates average outdoor humidity. It performs well in warm, moderately humid summers but benefits from airflow to deter botrytis and powdery mildew in damp, crowded plantings. If you keep the room above 16 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 salvia splendens 'sizzler burgundy' sparingly. Feed every 2-3 weeks during the growing season with a balanced liquid fertiliser to support continuous bloom. Avoid excessive nitrogen, which encourages leaves over flower spikes. Container plants need more regular feeding than bedded ones. 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 salvia splendens 'sizzler burgundy' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Leggy, sparse plants — From too little light or no pinching. Grow in full sun and pinch young plants to promote branching and more flower spikes.
• Wilting in dry heat — Less drought-tolerant than many bedding plants, it flags if the soil dries out. Keep evenly moist and mulch beds to conserve water.
• Powdery mildew and botrytis — Develop in humid, crowded, poorly ventilated plantings. Space plants for airflow, water at the base, and remove affected foliage.
• Aphids and whitefly — Feed on soft new growth and flower spikes. Rinse off and treat with insecticidal soap if infestations build.

Propagation

The Sizzler series is seed-raised, so it is most easily grown from seed sown indoors in late winter to early spring, germinating warm at around 21-24°C with light. Softwood cuttings can also be rooted to overwinter selected plants frost-free. 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

Salvia splendens 'Sizzler Burgundy' is mildly toxic to pets. Salvia splendens (scarlet sage) is not individually listed on the ASPCA database; the ASPCA 'Scarlet Sage' entry refers to the different species Salvia coccinea, listed as non-toxic to dogs, cats and horses. Because S. splendens itself is not ASPCA-confirmed, treat with caution and verify with a vet. Ingestion may cause mild gastrointestinal upset such as vomiting in 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.
