Anthurium clarinervium also called as Velvet Cardboard Anthurium, is a species of the genus Anthurium. This species was described by Eizi Matuda in 1952. It is a green room plant that is known for its striking veins on the leaves.
IDENTIFY ANTHURIUM CLARINERVIUM - VELVET CARDBOARD ANTHURIUM
Anthurium clarinervium is probably endemic to Mexico, known only from areas with limestone outcrops between the Rio Grijalva and Rio de la Venta, north of Ocozocoautla de Espinosa, Chiapas, at 800 to 1200m elevation.
It is a terrestrial species, deeply rooted among rocks, less frequently epipetric in thin soil on rock. This species is recognized by its broadly ovate, velvety leaf blades with all principal veins much paler than the surface and with a very narrow or closed sinus. The blades have basal veins usually free to the base or coalesced into a short posterior rib that is never marginal.
Velvet Cardboard Anthurium has been confused with Anthurium leuconeurum, which also purportedly originates from southern Mexico but whose exact origin is unknown. The latter species is distinguished by having a generally larger, more narrowly ovate blade with an obovate or hippocrepiform sinus and a conspicuously well developed, naked, posterior rib (i.e., it is marginal to the sinus).
ANTHURIUM CLARINERVIUM- VELVET CARDBOARD ANTHURIUM CARE AND CULTURE
Cultural information should only be used as a guide, and should be to be adapted to suit you. Your physical location; where you grow your plants, how much time you have to devote to their care, and many other factors, will need to be taken into account. Only then can you decide on the cultural methods that best suit you and your plants.
Light:
Anthurium clarinervium love shade. Long exposure to direct sunlight will typically burn flowers and foliage. Give them a good shady area to grow. However, do not deprive them of all sunlight. Ideally 75-80% shade is best. Extremely low light levels can shut down flower production. If that happens, move your anthuriums to an area that receives more light and wait for flower production to resume.
When grown indoors the plant will take about as much light as you can provide them with - but not direct sunlight. Place plant in an area with good, bright, diffused light. Try to place the plant between 5 and 8 feet from a window.
Temperature:
Velvet Cardboard Anthurium grow best with day temperatures of 25 to 32 °C and night temperatures of 21 to 24 °C. A high temperature will results in drying of the foliage and flowers and finally ends with the fading of the plant. Night temperatures of between 4 to 10 °C can result in slow growth and yellowing of lower leaves. A temperature below 16 °C will kill the plant. It is also be affected by temperature above 32 °C.
Substrate and growing media:
Anthurium clarinervium grow best in a well-aerated medium with good water retention capability and with good drainage. A good medium needs to be able to anchor the roots and stem so that the plant will not topple over as it grows larger, yet provide sufficient moisture, nutrients, and aeration to the plant. Organic matter (i.e., wood shavings, sugar cane bagasse, tree fern chips, taro peel, macadamia nut shells, or coffee parchment), volcanic cinder, or an artificial medium (i.e., rockwool, polyfenol foam) can serve as a good medium to anchor roots for anthurium plant growth and flower production.
At some point in time, the plant will need to be repotted. Symptoms will include severe root massing at the base of the plant, bulging on the sides of the pot (if it's plastic), and overall loss of plant vigor. Repot your plant early in the year, when new roots start to grow. Use a 6 to 7 inch (15-16.25 cm) pot filled half way with rocks. When repotting, as much as possible try to match the same media that your plant is already growing in. This will help your plant to root faster into the new media.
Watering:
High humidity and moist media is highly preferred. However, over-watering can cause root damage and sudden yellowing of leaves. While the plant love moisture, they do not like saturated media. So make sure to monitor your watering. Light, frequent watering is preferred to heavy soakings. Let the soil dry out in between watering. If you live in a hot area, water about once every 2 to 3 days; if you live in a rainy area, then water as necessary. Don't forget a light misting on the leaves to help with the humidity.
Too much drying of the plant will cease the plant growth and burns the tip of the plant. This plant prefers a winter rest at 15 °C for about 6 weeks with little water. It helps plant to bloom profusely in the next season.
Fertilizer:
Most growers use a slow time-release fertilizer monthly on their plants. Their roots are very sensitive to uncoated quick-release fertilizers, which can burn their sensitive roots. Even powder organic fertilizers can cause root burn. Liquid fertilizers may be applied as foliar applications or incorporated at lower concentrations into surface irrigation water. Most foliar fertilizers for orchids will work well with anthuriums. Consistency will be the key.
Propagation:
Over time, Anthurium clarinervium will shoot multiple plants from the same pot. By careful division of the mother plant, you can create multiple plant clones from just one plant. Division will also provide each plant with actively growing roots, which will in turn give you faster plant recovery.
Cuttings will require more patience. Anthuriums, especially the older cut flower types, will become leggy and appear to be growing aerial roots. This is when you should consider taking cuttings. The cutting will consist of severing the leggy growth from the mother plant and planting it into a new pot. On top of cloning of your favorite anthurium, the mother plant will possibly send multiple shoots off of where you took the cutting. In time you will be rewarded with a fuller mother plant.
