Velvet Cardboard Anthurium
Anthurium clarinervium is native to Mexico and differs from the commonly cultivated Anthurium hybrids by having much smaller inflorescences. It is popular for its attractively patterned leaves, which can grow up to 30 centimeters in length. The total height of the plant can reach 50 to 70 centimeters.
Bright to partially sunny locations with morning, late evening and winter sun are welcome. The velvet cardboard anthurium can endure the scorching summer sun only if it is placed at least one meter away from the window during this time.
Anthurium clarinervium will tolerate some shading. The fact that it does not receive enough light can be seen in the leaves, which remain small and turn a green color.
Like many other anthuriums, Anthurium clarinervium grows epiphytically, as a so-called perching plant. It sits on the branches or in the forks of trees, but does not suck their sap like parasitic plants do.
Its roots like air. Therefore, it is good to use a loose and permeable substrate.
Peat-free mixes for vegetables or herbs have worked well for my anthuriums. They are fibrous and loose.
Dense substrates can be broken up with orchid bark. This can also be used on its own.
Allow the substrate to dry moderately between waterings; it should not dry out. It also should not be submerged for days at a time.
If there is water in the saucer or planter for a few hours during the hot summer weeks, it will not cause harm.
For the first year after purchase or repotting, Anthurium clarinervium does not need any fertilizer. Then, from the spring to the end of the summer, a liquid fertilizer for flowering plants, green plants, herbs and vegetables or orchids can be given every four to eight weeks.
The velvet cardboard anthurium will do well at room temperature throughout the year. If you want it to flower, a temperate winter at about 59 to 18°F (15 to 20°C) can be helpful.
