Yesterday-Today-and-Tomorrow Plant (Brunfelsia): Growing Guide & Toxicity Warning

Few plants perform a daily color-change magic show like Brunfelsia pauciflora—yesterday-today-and-tomorrow. Its flowers morph from purple (Day 1) → lavender (Day 2) → white (Day 3) over a three-day lifespan, creating a living gradient across the shrub. Fragrant, long-blooming, and stunning—but highly toxic.

• Family: Solanaceae (nightshade)
• Common Names: Yesterday-Today-and-Tomorrow, Morning-Noon-and-Night, Kiss-Me-Quick, Brazil Raintree
• Native: Brazilian rainforests

• Growth Rate: Moderate

The Color-Change Phenomenon

Each flower lasts exactly three days:

• Day 1 (Yesterday): Deep purple
• Day 2 (Today): Lavender
• Day 3 (Tomorrow): White

Since blooms open sequentially, the shrub displays all three colors simultaneously—a natural ombre effect.

⚠️ CRITICAL TOXICITY WARNING

All parts contain poisonous alkaloids (brunfelsamidine, hopeanine).

• Highest risk: Seeds and berries
• Vulnerable: Children, pets (dogs, cats)
• Symptoms of ingestion: Vomiting, anxiety, ataxia (walking difficulty), seizures, muscle tremors
• Skin contact: May cause dermatitis, rashes
• Action: Immediate vet/doctor if ingested. Wear gloves when pruning.

Do NOT plant where children/pets play unsupervised.

Growing in Ground (Zones 9–11)

Site Selection

• Light: Morning sun + afternoon shade (avoids scorch/fade)
• Soil: Rich, moist, well-drained, slightly acidic (pH 5.5–6.5)
• Space: 5+ ft from structures/other plants

Planting

1. Dig hole 2× root ball width, same depth
2. Amend soil with compost/silt/sand for loamy texture
3. Plant at same level as container
4. Water thoroughly; mulch 2–3"

Care

• Water: Keep consistently moist (not soggy); stop if water doesn't absorb in 15 sec
• Fertilize: Acid-loving fertilizer once yearly in spring
• Prune: Spring & early fall; maintain 3–4 ft for small gardens
• Humidity: Thrives in humid heat; mist in dry climates

Container Growing (All Zones)

• Pot: Large, drainage holes
• Mix: Fast-draining potting soil + peat moss
• Winter: Move indoors before frost; greenhouse/enclosed porch
• Light: Bright indirect; acclimate 2 weeks in shade before moving in/out
• Prune: Keep compact; doesn't reduce blooms
• Water: When top inch dry

Propagation

• Method: Softwood tip cuttings (current season's growth)
• Timing: Spring–early summer
• Medium: Moist perlite/peat; rooting hormone helps

Pest & Disease Watch

• Spider mites (dry heat) → mist daily, insecticidal soap
• Yellow leaves → check watering (over/under), nutrients, pH
• Generally pest-resistant if healthy

Design Uses (With Caution)

• Mixed shrub borders (away from paths)
• Wall/fence backdrop (complement with low flowers)
• Patio containers (elevated, supervised)
• Near windows/verandas for fragrance viewing

Brunfelsia is a botanical marvel—a daily color symphony with intoxicating fragrance. But its beauty carries danger. Grow it knowledgeably, place it thoughtfully, and enjoy the show from a safe distance.
