Anthurium gustavii Regel

• Genus: Anthurium
• Botanical Background: Described by Eduard August von Regel, this species has been an object of study for its distinctive leaf morphology and its contribution to ornamental horticulture

• Geographical Range: Native to the tropical montane forests of South America
• Environment: It naturally thrives in humid conditions with well-drained, organic-rich soils and a moderate climate, typical of cloud forest regions

Leaves

• Glossy, heart-shaped leaves
• Leathery texture and subtle
• Contrasting veining

Inflorescence (Spadix & Spathe)

• Modest inflorescence with a greenish spathe and a central spadix. The overall display is subtle, and while the scent is minimal, the structure is key to its pollination strategy

Growth Habit

• This terrestrial species exhibits a clumping growth habit through the development of rhizomes, enabling gradual spread in its native habitat

Light Requirements

• It flourishes in bright, indirect light, which helps maintain its vibrant leaf color without causing leaf scorch

Watering & Humidity

• Regular watering is essential, ensuring consistent moisture while avoiding excess water. High humidity levels support its tropical nature

Soil & Potting Mix

• A well-draining, humus-rich potting mix enhanced with perlite or orchid bark is ideal to mimic its natural soil conditions

Temperature & Fertilizer

• An ideal temperature range is between 65°F and 80°F

• A balanced fertilizer applied during the growing season will support healthy growth

Division & Cutting

• Propagation is most commonly achieved by dividing clumps or using rhizome cuttings, especially during the spring

Seeds

• While seed propagation is possible, it is less common due to variable germination rates and the controlled conditions required

Typical Issues

• Spider mites and mealybugs
• Fungal issues and root rot

Treatment Recommendations

• Includes the use of insecticidal soap or neem oil for pest control and ensuring proper drainage to minimize fungal infections

• The species is noted among botanical collections for its unique leaf structure and the historical significance of its early botanical descriptions

• Collectors prize for its rare and distinctive foliage, which adds a sophisticated tropical touch to curated indoor gardens

Wild Population Status

• While detailed conservation data is limited, habitat loss in its native regions remains a concern that may impact wild populations

Market Availability

• This species is considered rare in cultivation and is typically available through specialized growers or botanical exchanges
