Anthurium magnificum and Anthurium crystallinum are popular houseplants, recognized for their striking foliage. Native to the rainforests of Central and South America, these aroids are often confused due to their similar appearances. Understanding their specific differences can help enthusiasts appreciate their unique qualities and provide appropriate care. This guide clarifies the distinctions between these two captivating plants.
Distinctive Visual Characteristics
Their leaves offer distinguishing features. Anthurium magnificum typically has a rounder, broader leaf shape, while Anthurium crystallinum leaves are generally narrower and more heart-shaped. Mature A. magnificum leaves are often a lighter green with more prominent veins, contrasted by the darker green or reddish hue of A. crystallinum leaves.
A notable difference lies in their leaf texture. While both have a velvety feel, Anthurium crystallinum leaves can also appear glossy or have a subtle shimmer. New leaves on A. crystallinum often emerge with a bronze or reddish tint before maturing to green.
Venation provides another clear distinction. Anthurium magnificum exhibits more pronounced veins that are lighter in color compared to the leaf blade. Anthurium crystallinum is recognized for its striking pale green or silvery-white veins, which create a strong contrast against the deep green foliage.
The most reliable way to differentiate the two plants is by examining their petioles, the stalks connecting the leaf blade to the stem. Anthurium magnificum is characterized by its quadrangular or squared petioles, often with subtle wings or ridges. Conversely, Anthurium crystallinum has smooth, circular petioles. This petiole shape remains a consistent identifier, even in hybrid varieties where leaf characteristics might be less distinct.
Growth Habits and Mature Size
Their overall growth habit and mature dimensions also vary. Anthurium magnificum tends to be a more robust grower, often reaching a height of 2 to 5 feet, with leaves that can grow up to 15 inches long and 10 inches wide. This species is known for its vigorous and rapid growth, potentially demanding more space as it matures.
Anthurium crystallinum, while still capable of impressive size, generally maintains a more compact form. It typically grows to about 1 to 2 feet tall indoors, though leaves can reach lengths of over 18 inches. Both species are considered slow growers, with A. crystallinum often producing a new leaf every 4 to 6 weeks.
Anthurium magnificum is generally described as a terrestrial plant, meaning it grows rooted in the ground. Anthurium crystallinum, however, is an epiphytic perennial in its natural habitat, growing on other plants or trees without harming them, deriving nutrients from the air, rain, and debris. This epiphytic nature influences its growth pattern, often leading to a self-heading growth habit where leaves take up lateral space.
Optimal Growing Conditions and Care
Both Anthurium magnificum and Anthurium crystallinum are tropical plants that thrive in warm, humid environments, mimicking their native rainforest conditions. They both prefer bright, indirect light. Direct sunlight can scorch their sensitive leaves, so filtered light, such as near an east-facing window or diffused by a sheer curtain, is ideal. While A. magnificum can tolerate slightly lower light conditions, A. crystallinum prefers brighter indirect light to enhance its crystalline leaf appearance.
High humidity is beneficial for both species, with ideal ranges often above 60%. For A. crystallinum, levels above 70% or 80% are recommended for optimal foliage. Maintaining temperatures between 65°F and 85°F is suitable for both, with temperatures below 60°F potentially causing damage.
Both Anthurium varieties prefer consistently moist soil, but they are highly susceptible to root rot if overwatered. Water when the top inch or two of soil feels dry to the touch, ensuring proper drainage. A well-draining and airy potting mix is essential, often composed of ingredients like orchid bark, perlite, coco coir, and peat moss to provide adequate aeration for the roots. Fertilization should occur during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength.
Availability and Market Value
The availability and market value of Anthurium magnificum and Anthurium crystallinum vary, influenced by their perceived rarity and demand among plant enthusiasts. Both have historically been sought-after plants in the houseplant hobby. Anthurium crystallinum is generally harder to find and potentially pricier than Anthurium magnificum.
Anthurium magnificum tends to be more accessible and affordable in the general market, making it a more common choice for those looking to add a large-leafed Anthurium to their collection. While prices fluctuate based on size, maturity, and vendor, the general trend indicates A. crystallinum often commands a premium due to its unique aesthetics and slower growth rate.
