Introduction & Overview

Common and Scientific Names

  • Scientific Name: Urospatha bogneri
  • Common Name: Bogner's Urospatha (not widely adopted)

Quick Facts

  • Origin: Tropical South America
  • Features: Large leaves and an unusual flowering structure; thrives in humid, shaded forest understories

Taxonomy & Classification

  • Genus: Urospatha
  • Botanical Background: Described by Muñoz-Castillo, Zuluaga, and A.Hay, this species represents a modern addition to aroids, reflecting ongoing discoveries in tropical botany.

Natural Habitat & Distribution

  • Geographical Range: This species is native to tropical regions of South America, with occurrences likely in lowland rainforests or the Andean foothills.
  • Environment: It naturally grows in high-humidity areas with well-drained, organic-rich soils, favoring shaded environments typical of dense forest understories.

Morphological Characteristics

Leaves

  • Large, heart-shaped leaves with a glossy texture

  • Deep green coloration

  • Robust texture makes them a standout feature

Inflorescence (Spadix & Spathe)

  • Elongated spathe enclosing a compact spadix

  • Subtle color variations throughout the inflorescence

  • May emit a mild scent to attract pollinators

Growth Habit

  • Terrestrial species that grows from a rhizome

  • Forms clumps over time, giving a bushy appearance

Cultivation & Care

Light Requirements

  • Thrives in bright, indirect light mimicking its natural forest understory

  • Avoids direct sunlight to prevent leaf damage

Watering & Humidity

  • Requires regular watering while maintaining well-drained soil to avoid root rot

  • High humidity is essential for healthy growth

Soil & Potting Mix

  • Prefers a well-draining mix enriched with organic matter

  • Containers should allow space for its expanding rhizome

Temperature & Fertilizer

  • Favors warm, tropical temperatures typical of humid climates

  • Apply a balanced fertilizer during the active growing season to support development

Propagation Methods

Division

  • Most common method: divide the rhizome during repotting

  • Ensure each segment includes roots and a growing point

Stem Cuttings (if applicable)

  • Can be propagated if cuttings include a viable growing point and root nodes

  • Best done during active growth for higher success


Seeds

  • Less common, but possible under controlled conditions

  • Requires consistent warmth and moisture for germination

Common Pests & Diseases

Typical Issues

  • Spider mites and mealybugs are common pests

  • Susceptible to root rot if overwatered or in poorly draining soil

Treatment Recommendations

  • Use organic insecticides like neem oil to manage pests

  • Maintain careful watering habits and ensure proper airflow to prevent fungal issues

Notable Traits & Uses

  • Unique inflorescence admired by collectors

  • Bold foliage stands out in tropical displays

  • Great for rare plant and aroid collections

  • Prized more for structure than flashy blooms

Conservation & Availability

Wild Population Status

  • Wild data is limited, but habitat loss is a concern


Market Availability

  • Rare in general cultivation

  • Found mostly through specialty collectors or exchanges
