Anthurium dalmauii Croat

• Genus: Anthurium
• Botanical Background: Described by botanist Thomas B. Croat, this species has contributed to the broader understanding of tropical aroid diversity and evolution.

• Geographical Range: Native to tropical regions, endemic to rainforests in parts of South America, with Ecuador being a noted region of occurrence.
• Environment: Naturally thrives in humid, shaded forest understories with well-drained, organic-rich soils. The species is typically found in areas with consistent moisture and moderate temperatures.

Leaves

• Large, glossy leaves that are deep green and marked by prominent veins, offering both aesthetic appeal and efficient light capture

Inflorescence (Spadix & Spathe)

• Consists of a slender spadix accompanied by a modest spathe that may show subtle color variations
• The flower structure is designed to attract specific pollinators, though it is generally unscented

Growth Habit

• Terrestrial, forms clumps from a short, creeping rhizome, making it well-suited for container cultivation as well as ground planting

Light Requirements

• Bright, indirect light, which mimics the dappled sunlight of its native understory habitat

Watering & Humidity

• Requires regular watering to maintain moist soil conditions and high humidity
• Care should be taken to avoid overwatering to prevent root rot

Soil & Potting Mix

• Prefers a rich, well-draining medium such as an aroid mix enriched with peat or organic matter
• A container with good drainage is essential

Temperature & Fertilizer

• Ideal growth is achieved within a temperature range of 65-80°F
• A balanced fertilizer applied monthly during the growing season supports healthy development

Division and Cuttings

• The most common method is through division of the rhizome during repotting, straightforward and maintaining the parent plant's characteristics

Seeds

• Feasible, though it is less common due to variable germination rates and a longer period before maturity

Typical Issues

• Spider mites and mealybugs
• Fungal root rot if conditions remain too moist

Treatment Recommendations

• Maintaining proper humidity and air circulation
• Organic insecticides and fungicides can be used

• Celebrated not only for its ornamental value but also for its role in advancing botanical studies of tropical aroids

• Collectors prize this species for its rare, dramatic leaf pattern and compact growth, making it an ideal specimen for curated tropical plant collections

Wild Population Status

• Not extensively documented, which underscores the importance of habitat conservation efforts for this species

Market Availability

• Due to its rarity, Anthurium dalmauii is generally available only through specialized collectors and niche nurseries
