Rhodospatha robusta Sodiro

• Genus: Rhodospatha
• Botanical Background: Described by Luis Sodiro, a key figure in South American botany, who contributed significantly to the study of tropical flora.

• Geographical Range: Native to Ecuador, this species grows in the humid lowland tropical forests
• Environment: Thrives in warm, humid conditions with rich, well-draining soil and a steady moisture supply, reflecting its natural rainforest setting.

Leaves

• Large and broad 
• Glossy deep green surface 
• Sturdy texture
• Undulating edges

Inflorescence (Spadix & Spathe)

• Prominent spadix surrounded by a broad spathe that ranges from greenish to yellowish
• Strong scent and relies on specialized pollinators

Growth Habit

• Terrestrial species grows in clumps from a central rhizome, forming a dense rosette of leaves

Light Requirements

• Bright, indirect light, similar to the dappled sunlight in its native understory

Watering & Humidity

• Regular watering is key to keeping the soil moist
• High ambient humidity is beneficial for its growth

Soil & Potting Mix

• A rich, organic, well-draining potting mix is ideal
• Containers should ensure excellent drainage

Temperature & Fertilizer

• Optimal temperatures range from 65 to 80°F
• Balanced, diluted fertilizer applied every 4 to 6 weeks during the growing season aids in healthy development

Division and Cuttings

• Most effective propagation is achieved through rhizome division during repotting, ensuring each piece has sufficient roots

Seeds

• Less common, fresh seeds require warm temperatures and consistent moisture to germinate successfully

Typical Issues

• Spider mites
• Fungal root rot

Treatment Recommendations

• Organic insecticidal soap
• Adjusting watering practices to prevent waterlogging

• Its striking appearance and its role within native ecosystems. The species is occasionally highlighted in botanical studies for its unique features
• Its robust form and eye-catching inflorescence make it a prized addition among collectors and botanical gardens

Wild Population Status

• Not widely classified as endangered, habitat loss in tropical regions is a concern, and ongoing conservation efforts are advisable

Market Availability

• Relatively rare in the commercial market, generally found among specialist collectors and in botanical institutions
