Caladium clavatum Hett., Bogner & J.Boos

• Genus: Caladium
• Botanical Background: Described by botanists Hett., Bogner, and J.Boos, Caladium clavatum has been subject to modern taxonomic scrutiny, reflecting ongoing research into the diversity of tropical aroids.

• Geographical Range: Native to humid lowland tropical forests.
• Environment: Thrives under shaded forest canopies with high humidity and moist, well-draining soils rich in organic matter, typical of tropical understory conditions.

Leaves

• Leaves are elongated and club-shaped, featuring a smooth texture and a mix of green with contrasting variegation
• Unique form contributes significantly to the plant's ornamental value

Inflorescence (Spadix & Spathe)

• Produces an inflorescence comprising a spadix and spathe
• Flowers are modest in size, adapted for insect pollination, and are secondary to the showy foliage

Growth Habit

• Terrestrial plant grows from a rhizome, forming clumps over time. Its growth pattern suits both container cultivation and garden displays

Light Requirements

• Performs best in bright, indirect light, which helps maintain its vibrant leaf patterns without causing sunburn

Watering & Humidity

• Requires consistently moist soil and high humidity levels
• Regular watering is key, with care taken to avoid waterlogging

Soil & Potting Mix

• A rich, well-draining potting mix enhanced with organic matter is ideall
• Containers should provide ample drainage to prevent root rot

Temperature & Fertilizer

• Prefers temperatures between 65°F and 85°F
• Balanced, slow-release fertilizer applied during the growing season promotes healthy foliage growth

Division

• Most common propagation method is through division of the rhizome

Cuttings

• Ensuring each division has at least one active growing point improves success rates

Seeds

• Propagation is possible, it is rarely practiced due to longer germination times and less predictable outcomes compared to vegetative division

Typical Issues

• Spider mites and aphids
• Fungal root rot if overwatered

Treatment Recommendations

• Organic insecticidal solutions like neem oil
• Ensuring proper soil drainage are effective strategies to prevent and treat infestations and diseases

• Club-shaped foliage of Caladium clavatum distinguishes it from other caladiums
• An interesting subject for botanical study and a conversation piece among collectors

• Prize this species for its unusual leaf shape and variegated patterns
• An exotic touch to tropical garden collections and indoor displays

Wild Population Status

• Limited documentation on its wild population
• No major conservation concerns have been reported
• Habitat preservation in tropical regions remains important

Market Availability

• Considered somewhat rare in cultivation compared to more common caladium varieties
• Sought-after addition for specialized collections
