Caladium tuberosum (S.Moore) Bogner & Mayo

• Genus: Caladium
• Botanical Background: Described by S.Moore and later reclassified by Bogner and Mayo, Caladium tuberosum represents significant work in the study of tropical aroids. Its documentation has contributed to understanding the diversity of tuberous aroids.

• Geographical Range: Native to tropical lowland rainforests in South America.
• Environment: Naturally grows in warm, moist conditions with rich, well-draining soils. It favors shaded areas with consistent humidity and filtered light, typical of rainforest floors.

Leaves

• Medium to large in size, displaying bold patterns with a mix of green hues and contrasting markings
• Smooth texture and an attractive, ornamental appearance

Inflorescence (Spadix & Spathe)

• Produces a typical aroid inflorescence with a slender spadix encased by a protective spathe
• Flowers are small and function primarily to attract insect pollinators

Growth Habit

• Terrestrial species grows from a tuberous rhizome, forming clumps over time. Its compact and vigorous habit makes it adaptable for container cultivation and tropical garden settings

Light Requirements

• Bright, indirect light is ideal to enhance its vibrant foliage without risking leaf scorch

Watering & Humidity

• Regular watering is necessary to keep the soil evenly moist
• High humidity, similar to its native rainforest conditions, is beneficial for optimal growth

Soil & Potting Mix

• A rich, well-draining potting mix with ample organic matter is recommended
• Ensure that containers have proper drainage to prevent water retention and root rot

Temperature & Fertilizer

• Ideal temperatures range from 65°F to 85°F
  
• Balanced and slow-release fertilizer applied during the growing season supports vigorous growth and healthy foliage

Division and Cuttings

• Most common propagation method is through rhizome division
• Dividing the tuber during repotting ensures each new section has an active growth point for successful development

Seeds

• Propagation is possible, it is less common because germination rates can be variable and the process is slower compared to vegetative propagations

Typical Issues

• Spider mites, and mealybugs
• Fungal infections such as root rot if overwatered

Treatment Recommendations

• Utilize organic treatments like neem oil or insecticidal soap to manage pests
• Ensuring proper watering practices and good air circulation helps prevent fungal issues

• Robust tuberous rhizomes of Caladium tuberosum support its vigorous growth and enable it to survive in challenging tropical conditions
• Distinctive foliage has made it a subject of interest in botanical studies of aroid diversity

• Enthusiasts prize this species for its bold, decorative leaves and its ability to thrive in controlled indoor environments
• Compact growth and striking appearance make it an excellent focal point in tropical plant collections

Wild Population Status

• No major conservation concerns
• Maintaining tropical rainforest habitats is essential for the long-term survival of many aroid species

Market Availability

• Moderately available through specialized nurseries and botanical collections, appealing to dedicated collectors and tropical garden enthusiasts
