Physical Description

1. Inflorescence:

   • Produces the largest unbranched inflorescence in the plant kingdom, reaching up to 3 meters (10 feet) in height.
   • Consists of two main parts:
     • Spadix: A central column that produces the odor.
     • Spathe: A large, petal-like bract that wraps around the spadix and opens during flowering.

2. Smell:

   • Emits a pungent odor similar to rotting flesh to attract pollinators like carrion beetles and flesh flies.

3. Tuber:

   • A massive underground corm that can weigh up to 100 kg (220 lbs).
   • Stores energy for the inflorescence and vegetative growth.

4. Leaf:

   • Produces a single, umbrella-like leaf that can grow up to 6 meters (20 feet) tall and wide.
   • Functions as the photosynthetic structure during its vegetative phase.

---

Habitat and Distribution

• Native Range: Endemic to the rainforests of Sumatra, Indonesia.
• Habitat: Thrives in humid, tropical forests with rich, well-draining soils.

In cultivation, it is grown in botanical gardens worldwide but remains extremely rare due to its challenging growth requirements.

Life Cycle

1. Tuber Dormancy:

   • The plant starts as a large underground corm (tuber), which remains dormant until environmental conditions are favorable.
   • Dormancy lasts several months to a year.

2. Vegetative Growth:

   • The tuber produces a single, massive leaf that lasts 1–3 years. This phase allows the plant to photosynthesize and store energy.

3. Inflorescence Development:

   • After sufficient energy storage, the tuber sends up the inflorescence. This takes several months to develop.

4. Flowering:

   • The spathe opens for 24–48 hours, releasing its foul odor to attract pollinators.
   • If pollinated, the spadix produces bright red berries that contain seeds.
   • If not pollinated, the inflorescence collapses, and the plant re-enters dormancy.

5. Seed Dispersal:

   • Seeds are dispersed by animals that eat the berries in the wild.

Blooming Characteristics

• Frequency: Rare; blooms occur every 7–10 years under ideal conditions.
• Duration: Blooms last only 24–48 hours.

---

Cultural Significance

1. Symbolism:

   • Represents rarity and uniqueness due to its size and infrequent blooms.
   • Often viewed as a marvel of nature because of its unusual appearance and odor.

2. Scientific Importance:

   • Studied for its unique pollination mechanisms and massive energy requirements.

3. Public Interest:

   • Its rare blooms draw thousands of visitors to botanical gardens, making it a significant attraction.

Care and Cultivation

1. Light:

   • Prefers bright, indirect light or partial shade.

2. Soil:

   • Requires nutrient-rich, well-draining soil.

3. Watering:

   • During the vegetative phase, water regularly to keep the soil moist but not waterlogged.
   • During dormancy, reduce watering significantly.

4. Temperature and Humidity:

   • Thrives in tropical temperatures (75–85°F or 24–29°C) and high humidity levels.

5. Propagation:

   • Can be propagated from seeds or by dividing the corm.

6. Fertilizer:

   • Use a balanced, slow-release fertilizer during the growing season.

Pests and Diseases

1. Pests:

   • Susceptible to aphids, spider mites, and mealybugs.
   • Controlled using insecticidal soaps or neem oil.

2. Diseases:

   • Root rot due to overwatering is the most common problem.
   • Fungal diseases can be treated with fungicides.

---

Chemical Treatments for Pests and Diseases

• Neem Oil: Effective against most pests, including spider mites and aphids.
• Insecticidal Soap: Safe for treating soft-bodied insects.
• Fungicides: Products containing copper sulfate can treat fungal issues.

---

Threats and Conservation

1. Natural Threats:

   • Habitat loss due to deforestation and agriculture in Sumatra.

2. Conservation Status:

   • Listed as “Endangered” by the IUCN.
   • Efforts include cultivation in botanical gardens and seed banks.

---

Interesting Facts

1. Record-Holding Plant:

   • Holds the record for the largest unbranched inflorescence in the world.

2. Heat Production:

   • The spadix heats up during blooming to help disperse the odor over long distances.

3. Longevity:

   • The tuber can live for decades, producing multiple blooms over its lifetime.
