Anthurium acutum is a rare epiphytic subshrub endemic to the Atlantic Forest regions of Brazil, specifically from São Paulo to Santa Catarina. This species is characterised by its elongated, lanceolate leaves and a compact growth habit, making it suitable for indoor cultivation. It is an excellent candidate for those interested in growing unique aroids indoors, particularly in conditions mimicking its native habitat.

This species thrives in humid, shaded environments in the wild, often growing on other plants as an epiphyte. When cultivated indoors, it benefits from a carefully controlled environment that replicates its natural rainforest conditions, allowing it to flourish.

Native to:
Anthurium acutum is native to the wet tropical biomes of Brazil's Atlantic Forest, particularly in the states of São Paulo, Paraná, and Santa Catarina. In its natural habitat, it thrives as an epiphyte, growing on other plants in humid, shaded environments.

Water:
Maintain consistently moist soil for Anthurium acutum, allowing the top few centimetres to dry out between waterings. Overwatering can lead to root rot, so ensure the potting mix offers excellent drainage.

Light:
Provide bright, indirect light to mimic the dappled sunlight of its native forest understory. Direct sunlight can scorch the leaves, while insufficient light may hinder growth.

Humidity:
High humidity levels, around 60–80%, are essential for this species. Regular misting or placing the plant on a tray of moist pebbles can help maintain adequate humidity. Its preference for elevated humidity makes it well-suited for terrarium cultivation.

Temperature:
Anthurium acutum prefers warm temperatures between 18–25°C. Avoid exposing the plant to temperatures below 15°C, as it is sensitive to cold drafts and sudden temperature fluctuations.
