Caladium stevensonii Croat & Delannay

• Genus: Caladium
• Botanical Background: Described by botanists Croat and Delannay, Caladium stevensonii reflects modern systematic research on tropical aroids and contributes to our understanding of the diversity within the genus.

• Geographical Range: Native to humid tropical rainforests in South America.
• Environment: Thrives in warm, humid conditions with rich, well-draining soils. The species prefers shaded, forest understories with consistent moisture and moderate light.

Leaves

• Medium-sized and heart-shaped with a smooth texture
• Striking color patterns that include shades of green and lighter variegation, adding to the plant's ornamental appeal

Inflorescence (Spadix & Spathe)

• Produces a typical aroid inflorescence with a slender spadix enclosed by a spathe
• Modest flowers attract insect pollinators but are secondary to its decorative leaves

Growth Habit

• Terrestrial plant grows from a rhizome and forms clumps over time. Its compact habit makes it suitable for container cultivation and small-scale tropical garden displays

Light Requirements

• Bright, indirect light is recommended to enhance its vibrant foliage without risking leaf burn

Watering & Humidity

• Regular watering is essential to maintain evenly moist soil
• High humidity levels, similar to its native tropical habitat, support its growth

Soil & Potting Mix

• A rich, well-draining potting mix with added organic matter is ideal
• Use containers with sufficient drainage to avoid root rot

Temperature & Fertilizer

• Optimal temperature range is between 65°F and 85°F
• Balanced and slow-release fertilizer applied during the growing season will promote healthy development

Division and Cuttings

• Most common propagation technique is rhizome division
• Dividing the plant during repotting ensures each new section includes an active growth node

Seeds

• Propagation is possible, but it is less frequently used because of variable germination rates and a longer period to maturity

Typical Issues

• Spider mites, mealybugs, and fungal root rot, particularly when overwatering occurs or air circulation is poor

Treatment Recommendations

• Organic treatments such as neem oil and insecticidal soaps
• Proper watering practices and improved airflow, effectively manage pests and prevent disease

• Noted for its distinctive leaf patterning, which has captured the attention of botanists and horticulturists alike
• Aesthetic appeal contributes to its cultural significance in tropical ornamental gardening

• Enthusiasts prize this species for its unusual foliage and compact form
• An excellent focal point in indoor tropical collections and small outdoor displays

Wild Population Status

• Specific conservation data are limited
• Preserving tropical rainforest habitats is essential for the continued survival of species

Market Availability

• Relatively rare in cultivation, making it a sought-after specimen among dedicated aroid collectors and specialty nurseries
