Nicotiana alata 'Perfume Deep Purple' (Perfume Deep Purple Flowering Tobacco) care

Light

Most houseplants will scorch where nicotiana alata 'perfume deep purple' thrives. Give it the windowsill you'd otherwise leave empty because everything else burned there. Full sun to part shade. Full sun maximises flowering, while light afternoon shade is welcome in hot climates and can intensify evening fragrance and bloom longevity. A plant moved abruptly from low light to direct sun bleaches in 48 hours — always acclimatise over a week.

Watering

Aim for when the top 2-3 cm of soil is dry, roughly every 4-7 days for nicotiana alata 'perfume deep purple', but treat that as a starting point rather than a rule. A south-facing summer windowsill will dry the pot twice as fast as a north-facing winter room. Lift the pot; if it feels noticeably lighter than it did wet, water it. Keep soil consistently moist but not soggy; flowering tobacco dislikes drying out and will wilt quickly. Water at the base and check containers daily in heat.

Soil and pot

Nicotiana alata 'Perfume Deep Purple' grows best in fertile, moisture-retentive but well-drained soil. Prefers humus-rich, compost-amended loam that holds moisture yet drains freely, at a near-neutral pH. Avoid waterlogged ground, which causes root and stem 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

Nicotiana alata 'Perfume Deep Purple' sits happiest at around 40-65% humidity and 16-27°C (61-81°F). Enjoys moderate to slightly high humidity and stays lush where summers are not arid. In dry heat it wilts and flowers fade faster, so maintain steady soil moisture. 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 nicotiana alata 'perfume deep purple' sparingly. Feed every 2-4 weeks during growth and flowering with a balanced liquid fertiliser, or work slow-release feed into the bed at planting. Steady feeding supports its continuous bloom; container plants need more frequent feeding than those in the ground. 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 nicotiana alata 'perfume deep purple' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Wilting in heat or dry soil — Flowering tobacco droops rapidly when soil dries. Maintain even moisture, mulch to conserve water, and provide afternoon shade in hot climates.
• Sticky foliage trapping debris — Glandular hairs make leaves naturally sticky; this is normal, not a disease. It can, however, trap small insects and dust, so simply rinse foliage if needed.
• Aphids and tobacco budworm — Aphids cluster on tips and budworms chew flowers and buds. Hose off aphids or use insecticidal soap; hand-pick budworms in the evening when active.
• Powdery mildew or grey mould — Damp, crowded plantings invite fungal disease. Space plants for airflow, avoid wetting foliage, and remove affected leaves promptly.

Propagation

From seed. Start indoors 6-8 weeks before the last frost; surface-sow the tiny seeds and do not cover, as light is required for germination at around 20-22°C over 1-3 weeks. Transplant after frost danger passes; many strains self-seed in mild gardens. 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

Nicotiana alata 'Perfume Deep Purple' is toxic to pets. ASPCA-listed as toxic to cats, dogs, and horses. All Nicotiana species contain nicotine and related pyridine and piperidine alkaloids (including anabasine and nornicotine). Signs include initial hyperexcitability followed by depression, vomiting, incoordination, rapid heart rate, and in severe cases paralysis or death. Keep away from pets and call ASPCA Poison Control if ingestion is suspected. 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.
