Anthurium Crystallinum vs Clarinervium: What Is The Different Between Them?

Who wouldn’t be amazed by the sight of Anthurium Crystallinum or Anthurium Clarinervium? The striking silver veins running through their large green leaves are truly captivating. I recall the first time I saw them, a few years back. It was almost impossible to look away.

The key distinction between Anthurium crystallinum and Anthurium clarinervium lies in their foliage. Anthurium crystallinum boasts slimmer, bright green leaves, while Anthurium clarinervium’s leaves are wider and a darker shade of green. Additionally, Anthurium crystallinum tends to grow more quickly compared to Anthurium clarinervium.

Anthurium crystallinum originates from the rainforests of Central and South America, making it unsuitable for outdoor cultivation. Conversely, Anthurium clarinervium is prevalent in Mexico, where the climate is more similar to that of the US. However, it is still advisable to grow Anthurium clarinervium indoors.

One notable difference is that Anthurium crystallinum’s leaves are thinner and more susceptible to damage, while Anthurium clarinervium has thicker, more durable (leathery) leaves. This also means the silver vein pattern on Anthurium crystallinum is more pronounced compared to its counterpart.

Both species feature heart-shaped leaves, yet the heart shape of Anthurium clarinervium is more distinct. In contrast, the leaves of Anthurium crystallinum are more elongated.

Another point of distinction is in their leaf coloration. Anthurium crystallinum’s leaves are somewhat brighter, enhancing the visibility of its vein pattern, whereas Anthurium clarinervium has darker leaves, resulting in a subtler pattern.

Growth Rate

Both Anthurium crystallinum and Anthurium clarinervium are similar in size, typically not exceeding 30 inches in height when grown indoors, although Anthurium clarinervium is slightly smaller. They both reach widths of 15 to 20 inches.

A key difference, however, is their growth rate. Anthurium crystallinum grows much faster than Anthurium clarinervium. In identical conditions, Anthurium crystallinum will reach its full size much quicker than its counterpart.

Additionally, Anthurium crystallinum produces more buds and aerial roots, leading to a denser growth and quicker propagation. So, if you prefer a plant that grows rapidly and is easy to propagate, Anthurium crystallinum is the better choice.

On the other hand, the slower growth and propagation rate of Anthurium clarinervium mean it’s less readily available and typically more expensive than Anthurium crystallinum. This can make it a more challenging addition to your plant collection.

Another way to distinguish between these Anthurium species is by observing the color of their berries.

Initially, the berries of Anthurium crystallinum are white, but they gradually change to purple as they mature. In contrast, mature berries of Anthurium clarinervium are orange.

There’s also a difference in size: Anthurium clarinervium’s berries are larger, containing multiple seeds, whereas Anthurium crystallinum’s berries typically have just one seed each.

Moreover, Anthurium clarinervium tends to bloom more frequently and produces more flowers, leading to a greater seed output than Anthurium crystallinum. This contributes to its slower growth rate.

Reproductive strategies also vary between these species: Anthurium crystallinum primarily reproduces vegetatively, while Anthurium clarinervium favors generative (seed-based) reproduction.

Soil Requirements

Both Anthurium crystallinum and Anthurium clarinervium share similar soil requirements.

Firstly, the soil needs to be well-draining, mirroring their natural habitat in the jungle. There, these plants either spread their roots in the topsoil layer, which doesn’t retain excess water, or they attach themselves to the bark of large trees.

Secondly, the soil should be loose. Anthuriums struggle in dense, clay-heavy soil, where there’s a higher risk of root rot.

In their natural environment, the topsoil where Anthuriums grow is rich in undecomposed plant matter, leading to relatively high acidity. Consequently, these plants thrive in slightly acidic soil, with a pH range of 5.5 to 6.8.

Light Requirements

Anthuriums also have specific lighting needs. Naturally growing beneath large trees, they aren’t exposed to direct sunlight, but they still require sufficient light for photosynthesis. This means they shouldn’t be kept in deep shade. The dappled light under the canopy of tropical trees is what they’re accustomed to.

To replicate these conditions at home, avoid placing Anthurium crystallinum or Anthurium clarinervium in direct sunlight, like in front of a south-facing window. A better spot is to the side of a sunny window. They can also thrive in front of east or west-facing windows. The key is ensuring they receive at least six hours of indirect light daily.


Water Requirements

Anthuriums require more frequent watering during their active growth phase, which is from spring to fall. During this period, they should be watered once or twice a week. However, if the summer is particularly hot or you’re in the southern part of the country, watering may need to increase to three times a week.

In their natural habitat, Anthuriums experience conditions where the substrate partially dries out between rains. Aim to replicate this by allowing the substrate in your potted Anthurium to dry out to about a quarter of its moisture content. You can check this with your fingers or a moisture meter; if the top quarter of the substrate is dry, it’s time to water.

Over-watering can lead to root rot, so it’s crucial to use pots with drainage holes. During the plant’s dormant period in winter, reduce watering to once every 10-14 days, and limit the amount of water you use.

Growing Conditions

Being tropical plants, both Anthurium crystallinum and Anthurium clarinervium thrive in warm conditions. They grow best in temperatures above 65°F. They can withstand up to 85°F, but any hotter and their growth may stall.

In winter, these Anthuriums don’t require as much warmth as in spring or summer. However, they are not cold-resistant and can be damaged by temperatures below 55°F. Therefore, it’s important not to place them in a cold room during winter months.

Humidity is another crucial factor. These Anthuriums need higher humidity levels than many other indoor plants. The air should be at least 55-65% humid, though 75-85% is ideal.

To maintain such humidity levels, installing a humidifier near the plant is an effective, albeit not inexpensive, solution. Alternatively, misting the leaves at least once daily can also help increase humidity around the plant.
