Anthurium aciculare Croat

• Genus: Anthurium
• Botanical Background: The species was described by the esteemed botanist Thomas Croat, whose work has greatly contributed to the understanding and classification of tropical aroids.

• Geographical Range: Native to tropical regions of Central and parts of South America, this species is found in shaded, humid rainforests.
• Environment: Thrives under the canopy of dense forests where high humidity, warm temperatures, and well-draining soils prevail.

Leaves

• Narrow and needle-like with a glossy finish
• Medium to dark green in coloration
• Display a distinct acicular form

Inflorescence (Spadix & Spathe)

• A central spadix accompanied by a modestly colored spathe that may have subtle green or brown hues
• Flower structure typically attracts insect pollinators without producing a strong scent

Growth Habit

• Grows as a terrestrial or occasionally epiphytic plant, forming clumps from a robust rhizome system

Light Requirements

• Bright, indirect light similar to the dappled conditions of a forest understory

Watering & Humidity

• Regular watering is essential to keep the soil consistently moist
• Maintaining high humidity levels is beneficial

Soil & Potting Mix

• A well-draining, peat-based mix enriched with organic matter is recommended
• A pot with drainage holes aids in preventing waterlogging

Temperature & Fertilizer

• Ideal temperature range is between 65°F and 80°F
• Balanced ertilizer during the growing season supports its development

Division and Cuttings

• Propagation is most effectively done through rhizome division or node cuttings, ensuring each cutting has at least one viable growth point

Seeds

• Seed propagation can be attempted in controlled, high-humidity environments to encourage germination

Typical Issues

• Spider mites and mealybugs
• Root rot from overwatering

Treatment Recommendations

• Effective treatments involve the use of insecticidal soap or neem oil for pest control
• Ensure proper drainage to prevent fungal infections

• Uniquely narrow leaves set it apart from other aroids
• Plays an important role in the ecological makeup of tropical understories

• Enthusiasts value this species for its unusual leaf form and compact growth habit, making it a standout specimen in specialized collections

Wild Population Status

• Considered rare
• Ongoing conservation efforts aim to monitor and protect its natural habitat

Market Availability

• Typically available through specialized nurseries and among aroid collectors rather than in mainstream horticultural outlets
