Anthurium rzedowskii Croat

• Genus: Anthurium
• Botanical Background: Named by renowned botanist Thomas Croat in honor of the influential Mexican botanist, Rzedowski, this species has been the subject of both horticultural admiration and scientific inquiry.

• Geographical Range: Native to select tropical regions of Mexico, particularly areas marked by rich, undisturbed forest ecosystems.
• Environment: Grows in humid, shaded understories where well-draining soils, high organic content, and moderate temperatures prevail, making it ideal for the lush tropical climate.

Leaves

• Broadly heart-shaped
• Glossy, and deep green
• Exhibiting subtle veining

Inflorescence (Spadix & Spathe)

• Contrasting spathe and spadix typical of Anthurium species
• Not known for a strong scent, the color patterns are unique and play an important role in attracting pollinators

Growth Habit

• Grows terrestrially, forming clumps with a pronounced rhizomatous base
• Robust structure supports both foliage and inflorescence development

Light Requirements

• Bright, indirect light
• Direct sunlight can scorch the leaves, while too little light may stunt growth

Watering & Humidity

• Requires consistent moisture with high humidity
• Allow the top layer of the potting mix to dry slightly between waterings to avoid root rot

Soil & Potting Mix

• Optimal growth occurs between 65°F and 80°F
• A balanced, diluted fertilizer applied monthly during active growth supports healthy development.

Temperature & Fertilizer

• Thrives between 65–85°F (18–29°C)
• Balanced liquid fertilizer at half-strength every 4–6 weeks during active growth

Division and Cuttings

• Most commonly accomplished through division of the clumping rhizomes; separate smaller offsets to establish new plants

Seeds

• Tends to be more challenging due to low viability and slow germination rates; controlled conditions are necessary for success

Typical Issues

• Spider mites and mealybugs
• Fungal issues like root rot if overwatered

Treatment Recommendations

• Insecticidal soap or neem oil is effective against most pests
• Improved air circulation and careful watering practices help prevent fungal infections

• Named in honor of a noted Mexican botanist, Anthurium rzedowskii not only garners attention for its beauty but also for its contribution to botanical research

• Prized for its unusual inflorescence and striking leaf morphology, which make it an attractive addition to curated tropical plant collections

Wild Population Status

• Considered rare in its natural habitat, with some populations facing pressures from habitat disturbance

Market Availability

• Not widely cultivated commercially; it is often available only through specialty nurseries and dedicated collectors, contributing to its rarity and desirability
