Anthurium clarinervium Care: How to Grow Stunning Large-Leafed Houseplants

Introduction to Anthurium clarinervium

With its huge, uniquely textured heart-shaped leaves, the Anthurium clarinervium makes a stunning houseplant. This exotic aroid, also known by names like Anthurium Strangenii and Velvet Cardboard Anthurium, has become wildly popular due to its gorgeous foliage. Learning how to provide the right care allows you to enjoy this tropical beauty for years to come.

Overview of Anthurium clarinervium

Anthurium clarinervium belongs to the Araceae family, originating in the tropical rainforests of Mexico and Guatemala. Called Clarinervium for its distinctive velvety, veined foliage, this evergreen plant emerges as a houseplant in the 1990s and has soared in popularity for its bold, tropical look.

The foliage is the showstopper – leaves grow over a foot long and nearly as wide, with a deeply quilted texture and prominent white leaf veins. The leaves emerge a dark green but develop a blue-gray hue as they mature. Tiny white to greenish flowers may bloom in summer but aren’t very significant.

In ideal conditions indoors, Anthurium clarinervium will reach 2-3 feet tall and wide, remaining relatively slow-growing and compact compared to other Anthurium varieties. With the proper care, those stunning leaves will keep unfurling!

Natural Habitat & Origins

Native to humid tropical forests in Central America, Anthurium clarinervium grows as an epiphyte attached to tree trunks and branches where it receives dappled sunlight. These roots help explain its preferences for warm, humid conditions and well-draining but moisture-retentive soil. Replicating these elements helps keep your houseplant happy!

Growing Conditions

Anthurium clarinervium adapts well as a houseplant but does require some specific conditions. Factors like light, temperature, humidity, and soil moisture must be managed for your plant to thrive with strong, lush growth.

Anthurium clarinervium Growing Conditions

Light Requirements

This Anthurium grows best in bright, indirect light, making it an ideal houseplant. Place it near an east or west facing window where it will receive gentle morning or afternoon sun. A couple hours of direct sun is ok, but avoid intense southern sun which can burn the leaves.

If you don’t have a suitably bright spot, supplement with a grow light to give your clarinervium the illumination it needs to truly flourish. Insufficient light leads to small, dull leaves.

Temperature & anthurium clarinervium humidity

Warm temperatures between 70-85°F are ideal during the day, with 60-70°F at night. Average room for anthurium clarinervium humidity around 40-60% suits it well. Ensure plenty of air circulation to prevent fungal leaf diseases.

anthurium clarinervium soil Needs

Use a well-draining, moisture-retentive potting mix with compost or peat moss. Orchid mix or bark chips help provide aeration. Let the top inch or two of soil dry out between waterings. Keeping the soil consistently soggy will cause root rot.

Watering Requirements

When growing in bright light, Anthurium clarinervium needs a relatively high amount of moisture. Water whenever the top few inches of soil become dry, but don’t allow the plant to dry out fully. Use room temperature filtered water. Brown leaf tips indicate underwatering.

Caring for Anthurium clarinervium

Caring for Anthurium clarinervium

With the basics covered, just a bit of care will keep your clarinervium looking lush and beautiful in its indoor habitat:

Fertilizing

Use a balanced houseplant fertilizer at half strength and water in monthly during spring and summer. Reduce frequency to every 6 weeks in fall and winter when growth slows. Avoid over-fertilizing which can burn roots or leaves.

Pruning

Remove any dead, damaged, or unsightly leaves and stems to maintain the plant’s attractive appearance. Pruning also helps direct the plant’s energy into new growth.

Repotting

Repot annually in spring before the roots become too crowded using fresh houseplant soil. Move it to a pot one size larger with drainage holes. Take care not to damage the large root systems when repotting.

Propagating New Plants

You can propagate Anthurium clarinervium by dividing root ball offshoots from the mother plant, or by using stem cuttings. Either way, provide warmth and high humidity while roots establish on the new plantlets before potting up individually.

Troubleshooting Common Issues of Anthurium clarinervium

Troubleshooting Common Issues

Catch problems early by keeping a close watch. Monitor for these potential issues:

Leaf Tip Burn

Dry air, over-fertilizing, or intense sun causes brown crispy tips. Increase humidity, cut back on fertilizer, and adjust sunlight exposure.

Drooping Leaves

This signals under-watering – give the plant a thorough soak when the top few inches of soil are dry. Ensure warm enough temps and adequate humidity.

Leaf Spot Diseases

Bacterial or fungal leaf spots cause unsightly marks. Prune affected leaves, avoid overhead watering, allow soil to dry out between waterings and increase air circulation.

Leggy Growth

If your plant becomes spindly and sparse, increase light quality and intensity. Rotate the pot periodically so all sides receive light exposure. Prune to encourage bushy regrowth if needed.

Anthurium Clarinervium new leaf

  • New leaves are very delicate and susceptible to damage. Avoid touching or handling the new leaves until they have hardened off and matured. This usually takes 2-3 weeks.
  • Keep the plant out of direct sunlight while new leaves are developing. Bright, indirect light is best. Direct sun can scorch the tender new growth.
  • Maintain warm temperatures around 70-80°F. Cooler temps can make new leaves develop slower.
  • Keep humidity levels very high, around 80-90% if possible. Anthuriums love moisture. Set the pot on a pebble tray, use a humidifier, or mist frequently.
  • Avoid drafts and direct air flow on the new growth.
  • Continue to fertilize at 1/4 strength every 2-3 weeks as the plant is producing new leaves. This fuels growth.
  • Monitor watering to keep the soil consistently moist but not saturated. New roots often emerge along with new leaves.
  • Rotate the plant periodically so all sides get even light exposure as it grows.

With the proper care, the new anthurium leaves should unfurl successfully and mature into healthy adult foliage!

Why an anthurium leaves drooping and what to do about it?

  • Overwatering – Droopy leaves can indicate too much moisture around the roots. Anthuriums prefer soil that drains well and is never soggy. Allow the soil to dry out somewhat between waterings.
  • Underwatering – If the plant needs more frequent watering, leaves may start to droop before perking back up after drinking. Make sure soil is moist (but not soaked) at all times.
  • Low humidity – Anthuriums thrive in humidity around 60-90%. If the air is too dry, the leaves can lose moisture and start to droop. Use a pebble tray, mist frequently or use a humidifier to boost humidity.
  • Sunburn – Direct hot sun will cause anthurium leaves to wilt. Keep them in bright, indirect light instead. Drooping in full sun is a sign they need shade.
  • Cold temperatures – Temps below 55°F can make leaves droop. Move the anthurium to a warmer spot.
  • Pests – Insects like mealybugs and mites can cause leaf drooping if left untreated. Inspect undersides of leaves for signs of pests.
  • Overcrowding – If the pot is too small or roots are crowded, leaves may weaken and bend downward. Repot into a larger container.

With the proper adjustments to care, anthurium leaves should become firm and upright again.

Conclusion

With its huge quilted leaves and exotic tropical vibe, Anthurium clarinervium makes a fabulous (and fabulous-looking) houseplant! Caring for this beauty is easy when you fulfill its requirement for bright filtered light, consistent moisture, average room temps, and high humidity. A little attentive care allows you to enjoy a showstopper specimen. Anthurium clarinervium’s stunning leaves make a unique living work of art in any indoor space.
