Anthurium (Anthurium andraeanum)
The stunning Anthurium andraeanum, or Flamingo flower, offers waxy red spathes ideal for humid indoor settings or tropical gardens.
Complete Plant Information
Overview
The striking Anthurium andraeanum, widely known as the Flamingo Flower or Painter’s Palette, is highly valued for its long-lasting, brilliant, waxy inflorescences. These unique spathes contrast beautifully against the dark green, heart-shaped foliage, making Anthurium a premier choice for adding year-round tropical color indoors. Native to the humid rainforests of Colombia and Ecuador, this plant thrives where consistent warmth and moisture are supplied.
As an epiphytic evergreen perennial from the Arum family, Anthurium andraeanum requires specific care mirroring its native environment to produce its signature blooms. While it is commonly grown as an exceptional houseplant globally, it performs best in USDA Zones 11 and 12 outdoors under partial shade protection. Its architectural beauty ensures that the Anthurium remains a sophisticated focal point in any bright, humid setting.

How to Grow
When establishing Anthurium andraeanum, opt for a location that provides bright, indirect light or consistent part shade; avoid direct, harsh sun which will scorch the foliage. For container cultivation, mirroring the St. Louis approach, use a well-drained, peaty potting mixture, ensuring a layer of pot shards is placed at the bottom for drainage security. Consistent moisture is crucial year-round; the soil must not be allowed to dry out completely.
Maintain consistent watering, often requiring more frequent attention in active growth periods. While the plant does not require a winter dormancy, it thrives with regular temperatures in summer and a minimum of 60°F (15.5°C) during the cooler months. High humidity is strongly preferred for the best health of your Anthurium.
Repotting every two years is beneficial as it helps flush out unabsorbed minerals that can accumulate in the potting media. If aerial roots emerge above the soil line, cover them with sphagnum moss to help keep that root area moist and concealed. Be cautious when using insecticides, as some formulations may damage the delicate flowers of the Anthurium.
Landscape Uses
The primary use for Anthurium andraeanum is maximizing its value as a striking houseplant, requiring bright, high-humidity areas to mimic its tropical origins. For gardeners in its suitable zones (10 and above), it can serve as an exotic understory planting or accent plant where light penetration is filtered, such as beneath high canopies. Its bold textures also make it an excellent candidate for container groupings.
Beyond its visual impact in the landscape, the sophisticated flowers of the Flamingo Flower are highly sought after as a popular, exceptionally long-lasting cut flower. When incorporated into floral arrangements, the waxy spathes maintain their vibrancy for extended periods, making this Anthurium a valuable horticultural export.

Noteworthy Characteristics
Anthurium andraeanum, commonly called flamingo lily or painter’s palette, is native to Colombia and Ecuador and is an evergreen tropical perennial of the Arum family. It is celebrated for its waxy, palette-shaped, bright red spathes contrasting sharply with its dark green foliage, typically reaching about 16 inches tall. Each bloom features a creamy yellow spadix surrounded by the spathe, offering blooms nearly year-round under ideal conditions.
Tolerances
Potential Problems
Gardeners should remain vigilant for common tropical pests, including mealybugs, spider mites, whitefly, or scale insects affecting the Anthurium. Prevention often involves regular inspection and maintaining high humidity, as dry or drafty conditions stress the plant and make it susceptible. Foliage can easily scorch if exposed to too much dry air or strong drafts.
Fungal issues, such as rots, blight, and leaf spot, are primary concerns, usually stemming from overwatering or poor air circulation common when growing Anthurium andraeanum indoors. Ensure robust drainage and avoid wetting the foliage late in the day to minimize the conditions that promote fungal pathogens.
Frequently Asked Questions
What hardiness zones is Anthurium suitable for?
The Anthurium thrives best in USDA Hardiness Zones 11 and 12, indicating it must be protected from any frost.
How large does Anthurium grow?
Mature plants typically reach 1 to 1.5 feet in height with a spread ranging from 0.75 to 1 foot wide.
What sun exposure does Anthurium need?
This tropical plant requires part shade; it needs bright light but must be shielded from intense, direct summer sun to prevent leaf and spathe scorch.
When does Anthurium bloom?
When conditions are optimal, the Anthurium andraeanum blooms freely, often producing flowers throughout the entire year indoors.
Conclusion
The Anthurium andraeanum is indispensable for adding long-lasting, vibrant tropical flair to both indoor collections and suitable outdoor settings. Its unusual and durable spathes continue to make the Flamingo Flower a global favorite among houseplant enthusiasts. Before introducing this specimen, confirm your environment can consistently provide the bright light, warmth, and high humidity required for thriving Anthurium culture.
Companion Planting
When positioning Anthurium andraeanum in containers or shaded garden beds, select companions that share similar cultural needs, specifically bright, filtered light and consistently moist, well-drained soil. Excellent partners for this Anthurium include other moisture-loving understory tropicals like Calatheas, Marantas (Prayer Plants), or certain varieties of Philodendron. Grouping these plants also helps naturally raise the localized humidity around the Anthurium, promoting healthier foliage.
Common Mistakes
The most frequent error when growing Anthurium indoors relates to inconsistent moisture management and inadequate light. Allowing the soil to dry out stresses the roots, while overly saturated soil quickly leads to rot, a common danger for this sensitive genus. Furthermore, many new owners place their plants in spots receiving direct afternoon sun, confusing the plant’s need for “bright light” with direct exposure, which results in scorched spathes and leaves.
Design Ideas
Use the Anthurium as an accent plant on sheltered patios or as a vibrant replacement for traditional foliage plants in dimly lit entryways where indirect light is prevalent. Due to its moderate height (1-1.5 ft), it works perfectly as a middle layer in mixed container displays, allowing taller greenery to frame it while shorter, moisture-loving groundcovers spill over the container edge. The bright red spathes offer superb color contrast against white or dark gray architectural elements.
