Anthurium dressleri

Anthurium dressleri is not a beginner-friendly plant and requires expert-level care. It has very specific growing requirements that are difficult to meet in most homes, including precise low light levels (at or below 200 fc), high humidity (60-80%), specific temperature ranges, and careful watering. The plant is more susceptible to overwatering than many other species and can be challenging even for experienced growers.

Anthurium dressleri thrives in temperatures between 22-30°C (72-86°F) during the day and prefers cooler conditions at night, ideally in the low 70s to high 60s Fahrenheit (around 18-22°C). Cooler nighttime temperatures actually enhance the plant's dramatic dark coloration. As a tropical epiphyte, it cannot tolerate cold temperatures or frost.

Anthurium dressleri is an extremely slow-growing plant with a compact growth habit. It typically reaches only 20-25 cm (8-10 inches) in height with leaves 20-40 cm long. The stem grows at a rate of approximately 15mm per year, meaning it can take nearly 50 years to reach mature size. This compact habit makes it particularly useful for growers with limited space, though patience is required.

Yes, Anthurium dressleri does produce flowers typical of the Araceae family, featuring a spadix and spathe. However, this plant is primarily grown for its stunning dark, velvety foliage rather than its blooms. If you wish to propagate from seed, the plant must be blooming, though it may take 2-3 years from germination for plants to reach maturity and flower for the first time.

Several notable ecotypes and clones are recognized in cultivation. The Rio Guanche (RG) form is famous for its extremely dark purple-to-black new growth and nearly black mature leaves. The "Windy" clone from Hawaii features dark emergent coloration, while the Panamanian SKG clone displays more brownish new growth tones. The "Eastern" type is reportedly easier to cultivate than other variants.

Anthurium dressleri requires minimal pruning due to its compact growth habit and slow growth rate. The main pruning task involves removing dead, damaged, or yellowing leaves to maintain plant health and appearance. Use clean, sterilized scissors or pruning shears to prevent disease transmission when removing any foliage.

Repot Anthurium dressleri once every 2-3 years, preferably in spring or summer when the plant is actively growing. This plant does not have an extensive root system and won't mind being slightly pot-bound, so there's no need to rush repotting. Choose a pot only slightly larger than the current one and use a well-draining epiphytic mix.

Gently clean the velvety leaves of Anthurium dressleri with a soft, damp cloth to remove dust and maintain their dramatic appearance. Be very gentle as the velvety texture can be damaged by rough handling. Avoid using leaf shine products, which can clog the pores and damage the special velvety surface. Regular cleaning also provides opportunity to inspect for pests.

Anthurium dressleri can be propagated through stem cuttings with aerial roots or by division. Take cuttings with sharp, sterilized scissors and root them in well-draining medium—though cuttings can develop stem rot in soil, so many growers prefer semi-hydroponic methods. You can also remove sections of healthy aerial roots during repotting. New shoots and leaves typically develop within 4-6 weeks. Seed propagation is possible but challenging, requiring 2-3 years from germination to maturity.

Yellowing leaves on Anthurium dressleri are usually a sign of overwatering, which this species is particularly susceptible to. To prevent this problem, use a well-draining potting mix and allow the top inch of soil to dry out slightly between waterings. Check that your pot has adequate drainage holes and that the plant isn't sitting in water.

Brown, crispy edges on Anthurium dressleri leaves typically indicate the humidity is too low. This species needs humidity levels around 60-80% to thrive. If brown spots appear that are soft and black, this usually indicates fungal disease, most likely root rot from overwatering. Brown leaf tips can also result from light scorch if the plant receives too much direct sunlight.

Common pests include spider mites, aphids, mealybugs, scale insects, thrips, and fungus gnats. Regularly inspect foliage and treat infestations promptly with insecticidal soap or neem oil. The most serious disease is root rot caused by overwatering, which presents as soft black or brown spots on leaves. If root rot occurs, remove the plant from soil immediately, trim rotting roots, and rinse with diluted hydrogen peroxide solution (1 part 3% peroxide to 2 parts water).

Anthurium dressleri is best kept as an indoor plant in most climates. It can only be grown outdoors year-round in tropical regions that mimic its native Panama habitat with consistently warm temperatures (22-30°C), high humidity, and protection from direct sun. Growing this rare species outdoors can make it more susceptible to diseases and pest infestations. It is not cold-hardy and cannot tolerate frost.

Anthurium dressleri’s native range is the Americas.

Anthurium dressleri should be watered regularly, allowing the soil to dry out between waterings.

Anthurium dressleri loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

To ensure optimal growth, the Anthurium dressleri prefers bright diffused light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

The Anthurium dressleri is not in need of supplementary humidity. Most water is taken in by plants through their roots, thus soil watering is the most efficient way to provide humidity to your plants.

The Anthurium dressleri should be repotted either when it doubles in size or annually, whichever comes first. Providing new potting soil with all the vital nutrients annually is enough to support the growth of the plant, and thus, there is no need for fertilizer. Remember that plants derive their energy from the sun, not fertilizer.

Ploi's records do not contain confirmed information on the toxicity of this particular plant. In the event of accidental ingestion of plant material with questionable toxicity by you, a family member, or a pet, it is always a good idea to consult a healthcare professional.

During the cold period, it is common for Anthurium dressleri to go dormant and their growth may slow down, so waterings should be spaced out more during this period.
