Introduction & Overview

Common and Scientific Names

  • Scientific Name: Caladium stevensonii Croat & Delannay
  • Common Name: Mainly known by its scientific name

Quick Facts

  • Origin: Native to tropical rainforests
  • Features: Displays uniquely patterned leaves with vibrant color contrasts. Its distinctive foliage makes it a standout specimen for collectors

Taxonomy & Classification

  • 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.

Natural Habitat & Distribution

  • 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.

Morphological Characteristics

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

Cultivation & Care

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

Propagation Methods

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

Common Pests & Diseases

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

Notable Traits & Uses

  • 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

Conservation & Availability

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
